Random leaf yellowing

[raratt]

So after reading about these types of problems a little.One clue is its started at the tip and is moving inward.Or so it apears.This would eliminate some things.
Sorry i dont have an answer,my first guess was N def or root bound.

At this stage in bloom their need for N should be decreasing from what I understand. I know they are rootbound, but I am just getting what I can from them to change strains. They are the first clones I have made and I didn't have the heart to just pull them out.

Looks like a P deficiency to me.

I'll give them some 0-10-10 bloom nutes plus Calmag tomorrow and cross my fingers, I'll get my water pH down also first. Has anyone used phosphoric acid to reduce ph? I happen to have some on hand.

 

[polishpollack]

Isn't that acid usually used as pH down? I'm not sure.
I think a transplant into ffof would be a good idea, then just water and don't do anything else. It's possible to used too much of a bloom fert, especially in a small pot. be careful how you give that fert.
It's unlikely you're going to find a plant that smells less.

I am not looking for a plant that smells less, I just want one that is sweeter smelling and doesn't smell like a dead skunk in a tub of diesel fuel...lol They are what they are, I figure I have about a month left with them. I don't have the pots to upsize them to anyway. Consider it an oversized solo cup challenge.

 

[polishpollack]

I meant stink less. Good luck on the sweeter smelling part.

Found out my muni water supply has gone from 6.8 in the summer to 7.6 in the winter. I guess the inflow of new water into the aquifer has leached out some alkali into the water supply. Lesson learned. 1/2 Tsp of acid/gal worked to get pH down to 6.4 approx. Kick me now for not checking.

Fed bloom nutes, corrected pH to 6.4, and added Calmag on the 7th, yet I see no appreciable decrease in the yellowing of leaves. Should they be reacting to the nutes/mag by now?

 

[Beachwalker]

No improvement on condition. Calmag didn't seem to help.

PH 6.8 too high, pH 6.5 for best results

 

[raratt]

6.8 is a bit high I know, but it shouldn't cause a lockout, I know 6.5 is optimum.

Well it likely is. Is there a reason you don't properly pH your water?

 

[raratt]

Post #27 and #28: corrected pH to 6.4,

How about changing water schedule?Maybe less more often.

I only water when they are dry, I have a meter, and with them being in plastic pots it holds moisture longer, but thanks for the input.

No, yellow leaves never come back, they die and fall off. All you can do now is stop other green leaves from turning yellow and also dying off.

I understand that, I asked when I should see the rest of them stop yellowing to know I gave them what they wanted.
