Any help please!!! Should I be worried??

These leaves come from a 4' female AK in her 3rd week of flowering. Plants are in Pro-mix, 3 gal containers, feeding with FoxFarm. Only have one or two of these mid-level fan leaves doing this on plant. Otherwise they look great! Should I be worried?


HELP!!

It looks like a micronutrient deficiency, but since the tips are slightly burnt, my guess is that you are feeding her well.
If you are already using a micro nutrient, the I would back off the phosphorus . phosphorus toxicity looks like micro nute deficiency.

hope this helps

I'd be concerned. That is premature yellowing and it is happening for a reason. Do you have meter equipment? Moister, Ph, Nutrient meters? That is a more sure way of knowing. I hate to guess.

I'll back off on the phosporus feed and see what happens. Thanks!

I have been watching the pH and it has been staying fairly on target. I am watering in 3-4 day intervals. DOn't have anyway to tell the nutrient level but have been following FF schedule with about 75% dosage.
