What deficiency is this??

3 months old in Ffof. Using botanicare nutes. I've seen a few deficiencies but this one is strange. The leaves are a whitish yellow starting from the new growth. Anyone know what nute it is lacking? I have been using the same nutes for over a year now. Do they have a shelf life?

chemical nutes ? if yes check the runoff pH and EC

How far is your light? Canoeing of the leaves like that could indicate heat stress and the leaves look a little toasty

Room temp is 80 degrees. Lights are roughly 18 inches. Lights are 2 famurs 2000w led. Heat stress would make sense. I've never seen the new growth come out where the lower part of the digit is white. I thought I needed more nutes but it seemed to get worse when I added 1 more ml of pbp grow.

Yes I think. Its botanicare pure blend pro grow with natural and organic based plant food. Will check runoff next feeding for sure. And I'll keep you guys posted.

yeah probably salt accumulations and/or ph too high/low

Raise the lights up a touch, 18 inches is too close for the new growth. When I switched to Led initially I kept making this fuck up. Oops
