Leaves started changing colors

Hello Everybody!

I have leaves that are changing brightness of color in the leaves. The odd thing to me is, It is starting from the steam part of the leaves. Not all but some. I am worrying a tad. Or am I over reacting and just slow down.

Bref-over look of what I been doing and set up. I have a little hydro set up out of PVC 4", 40,000lems T5HOs above and on a wall. Wall one is not on as long as top. I use Humboldts' for feeding.



2main probs I see and seen.

1
Last week I over feed by oh a lot x.x I fixed that But I know I may have still over feed that week. Week before. I feed a nice light feed. This week I washed out and main tanks and so on. Ran clean water I let site out for 4 days. (Norm I do 2 to 3 days. But work got nuts) I didn't feed yet. For what little left overs may have been in places to where I couldn't get to easy.

2
my water temp is a not been easy to keep under control this week for some reason. It got as high as 80.1 F` I know that there is no fast way that the water heated up. Just slowly. Though I can cool fast by using filtered ice. But I never just added a shit ton at one time. For fear of shocking them.

Am I over worrying!? >.<

Thanks

New growth can appear a little yellow at first before it's had a chance to develop and green up. If those leaves don't green up like the ones under them, then you might have a problem. But it doesn't look that way to me.

80 degree water temp will cause problems. Get RO or distilled, fill empty water bottles, freeze. Drop one in as needed to keep temps down.

water bottle ideal is awesome! Thanks I have done that for diff things but never clicked to try that!

also here is 2 other pics. one is of same plant and another one.

same one

Lower the nutes, check the PH, add Calmag plus.

The plant looks fine, recovering from the overdose. The top leaves as stated before are fine, they should gain their color like the lower leaves in a day or two, no worries. A little clue I use is that if the newer leaf isn't as green as the lower leaves once the next set of leaves pop up then I know I need a touch more N in the mix. You have to watch the color of the lower leaves constantly though, if they start to appear too dark then you are too high on the N. It will all just come down to practice and learning your strain.
Good Luck

Thank you everyone for your replies!

The two little clones are looking a tad better today.

Now my other plant is acting up. When before she was not... :/

She is a older clone I got from a friend. (All 3 are really. one small clone is 707 and the small and big clones are Sugar Kush) She over 12" taller than the other two and to be a mother plant. The big leaf changed a lot faster than the other leaves on the little ones. I like to hope that this is a little normal for this kind of issue..? I did rinse all the roots yesterday one more time to get anything that may have been left over from over feeding. Which there was, x.x I fixed the PH in the water as well. It is flouting around 6 to 6.5ish.

But here is my baby soon to be mother.







Is this normal step/s in them all healing and fighting the ickies and on way to be healthy again?

Thank you as always!

That larger clone is suffering deficiency because it needs more than your smaller ones. Are you running these different sized plants on the same nute solution? If so, there's your problem right there. The new growth is feeding off the old growth because it's not getting enough food.

When I got them the 2 was same size and other one was 3 inches taller(or so). The taller one had a better root system on it than the other two. I figured cuz of that is why it is exploding as the other two are going slower.(roots are growing faster on the little ones than the leaves. I figured from transplanting them into my system from my friend, would take a little bit to adjust but not sure how long is ok and what not.) There is no nutes feeding any of them. 1st week feeding everything and one looked great. spec the bigger one. Till I over feed and maybe under feeding now? My res is a 20gl and I didHumboldt's feed chart for hydros(other than the over feed I made). So Should I add feed back and let it roll or should I really take the bigger one out?

ok seriously im no hydro grower but these fukin yahoo's on here are so quick to diagnose i dont even think they read what you typed just looked at pics and tossed out some bullshit diagnosis to make themselvs fele like they know what they are talking about.

PH is good?
whats your PPM?

you did the right thing by draining and flushing your system when you accidently OD them but you cant leave them with no nutrients, unlike soil hydro systems need to have nutes from day 1 as plain water does not offer these nutrients (maybe a little but in tiny amounts)

i personally suggest checking your PPM and slowly raising it daily while maintaining propper PH, ALL of your plants look like they are suffering from deficiency because they have been in plain water for 4-5 days with no food.

get a second opinion on this as im no hydro guy but from what i understand of the system this is your problem. also you need a good PH and PPM meter for hydroponics, get them, they are worth it 100%

lol SERIOUSLY DUDE, he said he flushed and didnt add ANYTHING. if your too fukin lazy to read the post dont offer help that can possible destroy his grow

First of all chill man, I did read HIS entire post and suggested what seemed best to do in this case, if you don't agree don't go all hater flaming other people's opinions.

As I see it, plants have suffered toxicity, you can clearly see burn tips from over fert and dark green leaves from to much N, of course this lead to lock out of elements and the plants suffered some slight deficiencies as consequence. Hi did right by flushing as the plants are now actually bouncing back even though the scars will remain.

I'd even lean towards salts built up or pH fluxs as the initial issue by looking at the nasty salts on top of the plugs and not the idiotic theory old growth is getting more food than newer, thats BS. So In my HUMBLE opinion, What he needs to do ASAP is to stabilize the medium and slowly rise ppms while making sure his PH and res temps keep in range, Calmag along with superthrive has worked BEST for me to get my plants out of trouble, running it for 2 days would be sweet! he could add some nutes as well but the solution should be soft. My point is that's proven that Cannabis grows WELL in a wide range available nutes, in fact they are the less important factor in the equation where pH and temps play a bigger role for availability and metabolizing, people mess up for having the concepts all wrong.

sorry for long reply. PC issues x.x

turned out the strips we was using for PH didn't work at all and very off. We got a new meter, though two days ago! instead of the strips.

The PH is now at 5.6
PH was 7.8 to 8.0 :/

The ec/ppm is at 890/445 in our 15gl res. (lite'ish feed after the over feed. Is this to low for a slow start back to normalish levels?)

Temp is still been a pain, in the 15gl res, If I baby it I can keep the water at 66 to 67f`But over night it heats back up x.x So... We got a 55gl res set up and almost ready to take the pump and rest of the linking pipes. I pre mixed everything and got the ec/ppm to 1300/650. The PH is at 5.7 right now too. There is also a powerhead(I have a lot of fish tank stuff) pump mixing the water plus a airstone. Should I stay with these levels or change them a little till no more yellow leaves show and everything is healthy again? I am still in grow stage. Should I add a more weeks to grow for healing, before I start flowering? (on top of the 4 weeks) Really hoping the res being 55gls and in another room will help keep temp under control.

How long you think it would take for them to be back to good health?

two weeks should be plenty.. remember to keep feeding them N until pre bud phase. I'm really glad you followed the right advice.

little stat-update n some pics too.

HP is kicking at 6.0

EC is at 2550 right now. (the book said, to fig out the ppm. cut the ec in half on this reader...?)
So ppm around 1275ppm's?

All the plants been looking better till this morn the bigger one started going more yellow again. I think it was cuz of the water temp yesterday. I worked over 16hrs(joy!) With holidays and no one else here to toss a ice pack in it climbed to 82f` in my old res. I finally got everything rigged up to the 55 drum with fresh water and everything. Stats was the same as the small tank with temp around 69f` atm. For the past many days water temp been around 66 to 70f`(just so you party ppl know)

this one is looking great. Just started to explode.


this one is doing a lot better too, until that yellow one popped x.x


little seedlings, doing pretty well I think/hope


The bigger girl. I cleaned off the bad yellow ones other day. Over all she been doing better...and these are the newer yellows, next two pics.

use 3 litre soda bottles full of water and freeze them, they should stay frozen for quite a while

I freeze 2litters and have like 10 going. I just ran out and got another timer. clearly the timer failed. it was failing slowly and I didn't know it. So hopefully. This will help n fix it. I am saving up for a chiller but they are pricy even for a cheap one. But like everyone is saying. I will need one sooner or later x.x

Does the pics look like it is a water temp issue? My gut thinks it is.

here is a pic of one of the leaves on the bigger clone.

still looks like deficiency to me but like i said before i really do not know, i dont like giving diagnosis on this stuff. i would wait for a second opinion. but if you said your PPM is aroun 1300 then it very well could be since the temps got too high but i was always under the impression high temps lead to root rot so may want to check the roots.

ok so a bit of reading and the high temps will cause lockout wich will look like a deficiency, the higher the temps the less O2 the water is capable of holding. this will cause a lockout, so there is a good chance your high temps caused a lockout and it looks like a deficiency.

best i can do for ya pal

The later pictures show magnesium deficiency. Look it up, it's very easy to diagnose. The fix is adding Calmag supplement. 5-10 ml per gallon.
