Yellowing Bottom Leaves

smillz · Sep 29, 2012

Hi, my plants were just put into flowering a few days ago. They are feminized great white shark, but the bottom leaves are yellowing... I'm using miracle grow moisture control potting mix with nuts added in. I used tap water that sits out for a few days and a 125 watt 2700K cfl... I haven't added nuts yet but plan on it when the plants need watering... I will flush them as well.

Any ideas what is causing the bottom leaves to yellow? Is it normal? Also what is causing the yellow spots on the leaves?

so you have`t been adding nuts yet .. and your in flowering .. there is your problem ..

yellow bottom leaf`s is a sign that it is in need of Nitrogen .. and use its stored up N. in the bottom grow ..

specialy the two fist weeks of flowering (the stretch) it will grow a lot and therefor need a lot of food ..

need to add some Veg nuts now and switch to bloom nuts in two weeks time ..

also .. your pots seems kind a small .. my best advice is do a quick repotting in to some bigger pots (3-5 gallon) with some fresh soil .. and start adding some nuts ..

Not sure mg potting soil is ideal for mj, that may be a sign of nute burn, that soil may have fert in it and may be too hot for your plant, not sure tho I'm not a soil grower, just my opinion.

I went ahead an added some veg nuts, didn't need to be watered but I'd rather have it droopy for a day than eating itself. Hopefully this stops the yellowing process.

Those bottom leafs turning yellow and dieing is normal. You have nutes burn from your mg on tips of leafs that's it the mg is burning the plant it'll be fine. If it spreaD's then worry.

Yeah the spots are pretty stable, just was concerned about the yellow bottom leaves... they literally yellowed in 12 hours. When I turned the lights off this morning they were green, and when I turned them back on they were yellow. :/

Yeah they are the first set your talking about right? They do that, If it keeps moving up to other leafs then worry but those bottom ones do that. Hope I could be helpful Happy growing.

maybe re-pot to larger pots before flowering

You might want to get rid of the very bottom leaves anyway, so they aren't sitting on top of the wet soil when you water.

Just a general update. I added some veg nutrients and the plants have responded with 2 inch growth per day. My question now becomes did I flower too early? I waited three weeks and the plants were about 6 and 8 inches tall. The larger plant is now about 10-11 inches tall, and the other about a 8-9. The top of both plants are showing sings of a flower forming, and I'm just concerned that I may have ruined my yield by flowering too early. Any thoughts?

The reason I opted for earlier flowering is because I'm low on space and light....

Slipon · Oct 1, 2012

nahh with a CLF your did it just in time I believe ..

you wont be able to keep good light for more then a foot anyway ..

and with small pots like that you cant expect to grow much bigger plants ..

I believe you would have been in trouble if you had waited much longer as root grow might have made it rootbound ..

but look in to LST for next time .. for multiply tops you can keep close to the light ..

remember to keep them buds forming with in 2-6 inch`s of the light .. just make sure they don't get to hot ..

bigrake · Oct 2, 2012

If your flowering early your yields not as big anyway so of course your yield will be smaller than someone vegging for 2 or 3 months. Your limited dove so you don't have a choice unless you find more space and light.

Do you think if I repotted the plants it would stress them into hermies, they are in day 6 of flowering. I'm heading to Walmart this evening to get 3-5 additional CFL's to place around the bottom of the plants. I was also thinking about getting bigger pots... Any suggestions, you mentioned 5 gallon pots?

Slipon · Oct 2, 2012

dont think it will curse any bigger problems ...

just make a smaller plants .. then if you have done it two weeks ago .. but I would do it .. I did similar .. later in flowering .. week 2-3

as you can see I did also try to stress it as littel as possible .. so I just cut the bottom out of the old pot and gave it a half full smaller pot to continue its grow .. worked .. kind a .. other plant yield more .. but I bet it would have been even worse with out ...

but in your case I wouldn't worry to much .. just do it now .. and do a gentle reporting .. do a littel research .. but in general

make sure you have the new pot ready with new soil in it (enough to make the old top soil the new top soil aswell)

use the old pot to make a hole in the new soil in the bigger pot .. make sure its moist (I use a spray in between I add soil with a drop of root power/kelp)

then your ready .. do it fast but carefully .. put your hand flat on the soil .. with the steam in between your fingers (like a big fat joint)
and tip it over ..

if it dont let go right away try to pat on the bottom with your free flat hand a few times .. if it still dont let go .. tip it back over and use a butter knife to loosen the roots from the pots side all around .. and repeat it all again ..

then moist the old rootball/soil and "drop" it in the new pot .. and add soil around the edges .. water it slowly till you see run off ..

make sure the soil you get have a PH for weed (between 6 and 7) a lot of cheap "Supermarket" soil is low (under 6) and not suited for weed ..

use them bucks on a good Organic soil and if possible with some Perlit in it .. if you cant get perlit use lega nuts or coco to make the soil light (use around 30% and 70% soil)

and yes a 5 gallon would be ok I guess .. how big is the one you have it in now ? go with sumthing twice as big ..

about CLFs .. get em in 2700K and as high Watt as possible .. 23W or 35W is them most use I guess .. beside them big once made for growing (100-300W)

do you use Y-splits ?

I currently have this exact set-up: http://www.lightbulbsurplus.com/index.php?main_page=product_info&cPath=622_7_80_738&products_id=2004
I haven't been using separate CFL spirals, but I'm looking into getting some today. I've never seen the Y-splitters like that for sale in Walmart, generally I only am able to find normal lamp fixtures. But regardless I intend to get at least the 25W bulbs. I'm thinking 225-275 watts should be enough for those two plants. The current Feliz 125 watt bulb plus 4-6 additional 25 watt bulbs...?

The one pot is currently 10 inches and the other 8 inches (I think these are in reference to the pot diameter). I'm not entirely sure how many gallons those would correspond to.

Slipon, I'm saying it the second time, you give good info, but could you try to write shorter and without three dots everywhere? Because basicalyy 1/3 of people reading are stoned and it's hard to understand/read so much. Thanks.

Slipon · Oct 2, 2012

lol then don't read em

and belive me I try, I could easily write much more

and I hope its more then 1/3 WTF would they do in here if not stoned ?

about CLFs
sure get 4-8 more smaller once, get them Y-splits if you can, place em around the bigger one.

that is atlest how I would go with it, that or get one more of the big one you have and use one for each, you realy need to look in to LTS if you plan on continuing to use CLFs

There's your problem with the yellow leaves. Not because it's normal. Leaves don't normally turn yellow til the plant is dieing. 90% of the time the yellowing leaves are caused by people starving their plants the last 2 wks with a flush.
If you do a proper cure you don't have to worry bout long flush periods which do nothing but starve the plant forcing it to consume itself which is all the yellowing leaves are

smillz · Oct 2, 2012

Okay, so I have added one 15 watt 2700K CFL and three 25 watt 2700K CFLs scattered around the plants plus the original 125 watt 2700K CFL on the top of the plants... They provide 860 lm+ (3)1600 lm+ 5000 lm for a grand total of 10,660 lumens. Is this enough light? I really cant physically add anymore light to the room, like right now I walk in there and I'm blinded and see spots when I leave (especially with the walls being white).

I had no luck finding Y-fixtures, so I settled with regular lamp fixtures, so there isn't much room left around the plants.

Tomorrow or Thursday I will transfer the plants into larger pots. The soil is currently too wet so I had almost no luck getting them out of the pot they are currently in without stressing them like crazy.

Slipon · Oct 3, 2012

sounds good .. and sure its enough .. atlest its more then before so it can only be better ..

and I know what your talking about .. you should try to take a close look at my 600W HPS or the maylor right next to it ..
cant see shit for minuts .. I use sun glasses in ther
