[Indy73]

Two plants one a clone and the other a seedling. One is 6 weeks from first flower n the other 4 weeks. Watering coco in 5 gal with ph 6.2. 75 degrees 45-50 humidity.

The dark green waxy leaves show N toxicity. The pale bleached out leave with interveinal chlorosis appears to be potassium or iron deficiency. Either PH problem or imbalanced feed. What are you feeding and what PH are you watering at?

Next time you water check input PH and the runoff.

I was thinking possible potassium. I jus didn’t know whether it was a deficiency or too much. I’m using Fox Farm. I stop using grow big almost a month ago. I use tiger bloom 3 ml liquid food 3 ml and a 1/4 tsp of chin Ching a gallon. Every now n then I add a lil cal/mag. I ph my water at about 6.1 or 6.2

When you say water... you mean fertigate right? All ater should have nutes. Your ph should be 5.9.

Whats your ec? In and out the bottom?

During veg it was around there but I was told to have it slightly higher for flower. I don’t really check my ec. If I do have a potassium deficiency this late in flower can they still bounce back from it
