Experienced grower stumped on a leaf issue.

WindyCityToker · May 25, 2012

OK so I have been around awhile and haven't seen this one. Anyways, this is a Big Buddha Seeds Blue Cheese. 2and1/2 weeks old

Happy Frog soil
250hps
using the GO line nutes but just gave the first 1/4 strength dose last night
Everything (temp,humidity,PH) is perfect
The Only other thing is I crushed Mosquito Dunks to cut down on fungus gnats (more of a pre-emptive really) She isn't infested And I've had good luck with them before.

And yes, I now the plant will probably be ok I'm not panicky

just stumped

Any Ideas? Thanks in Advance :leaf:

I would have to say its a ph issue, I know you say its perfect so I'm confused. Id flush it, check the run off ph and let it chill for a few days...

6.8 bro. Also should have mentioned i have 3 more in the same cab same everything and they are flawless thus far

WindyCityToker · May 25, 2012

And thanks for the quick response

lokie · May 25, 2012

what type of water? tap, well/city, softened, RO?

Nitegazer · May 25, 2012

I would guess that the 1/4 nutes, combined with whatever is soluble in the dunks, has given a slight burn to a pheno that is more sensitive than the others. I would just go back to straight water for the next feed cycle or two and see if the problem abates.

hmmmmm very interesting, I might also think chlorine from tap water, but the others are not showing the same signs. I must admit I'm stumped as well. I'm going to see what I can find on this..I can't wait to see what others say about this. very smart people here!

Don't feed seedlings or put them in rich soil.

Look at mine at 3 weeks old. In seedmix (soiless) and fed 1/4 - 1/2 strength Rhizotonic at EC 0.2-0.3.

I've had to transplant them out already as they were becoming rootbound. Now they're in soil, age 3 weeks !!! I still won't be feeding them for a couple of weeks.

WindyCityToker · May 25, 2012

I'm on filtered tap, letting it sit out for 48hrs.

And thanks for lots of helpful advice.

lokie · May 25, 2012

how filtered? a water softener or a full blown RO system. A softener would have lots of salt and you woul;d have seen problems long
before now. if RO could it be the start of a cal/mag def? i do not know as i have yet to experience cal/mag def.

thats your problem Don't let it sit out 48 hrs plants also need clorine if you let water sit out 48 hrs your ph and clorine drops would like to smack the clown that thought of letting water sit out prior to feeding
Farmers must have million gallon containers to let there water sit out before watering there fields hahahaha
Chlorine is also an essential nutrient, but not much attention has been paid to it until recently. There is a current debate as to whether silicon, nickel and cobalt are also essential nutrients.

that's nute burn..............that's what it looks like. shouldn't be, on 1/4 strength, but walks like a duck.............

Cannabis is happiest with chloride levels below 1ppm. My micros include nickel, cobalt and silicon ... also chromium.

To OP: I'm tending toward mild nute burn. Happy Frog "as supplied" gave me months of well-fed growth; i only began supplementing in flower. If your pheno has the nute sensitivity of my dear departed Widow, that would clinch it for me. cn

So whats your point ????? you should be feeding there looking rather small heres mine 8 weeks veg under 136 watts of flourescents can you see a difference i sure can even in cups they were fed 650 ppm now there @ 1150

everyone is starting to worry to much about clorine its needed you ever wonder why so many growers are having issues cause of letting there water sit just go and get a cup of water check ph in it and leave it for 24 hrs see how much it drops you most of the time growers leaving there water out obviously fedding there plants with ph of around what 5.8 what nutrients start locking out personally i would give it a shot of food with proper ph and mixed straight into tap water not sitting out everyone tends to think all of a sudden to much when it can be to little of nutrients

Possibly fungus?
Try neem oil?

A one mth old clone has the same hormones as a 2 mth old mum. Point being that seeds are different and need to be started a lot slower. Your pic is of a clone and was prob passed over rooted. The more root system it has the more food they can take.

you should be feeding there -

and you should never feed when u are about to transplant into new soil (EC 0.8-1.0)

Is this guy serious? WOW! Plants like chlorine..wtf? The best way to rid chlorine in tap water is to let it sit out 24 hours, any hydro grower knows that!...farmers don't let there water sit out....sorry to break it to you pal..but we aint growin corn!!! Learn before you post such nonsense!

5.8ph is good for hydro. Don't confuse hydro with dirt.
