Hey it looks like nitrogen deficiency. Buds are taking nitrogen from the leaves and not the soil. Hope this helps happy growing.

Another thing to look at is where/what. Where/What leaves are affected. Old/bottom or new/top. My guess is N, P, and K, unless you have re potted recently.

Nitrogen deficiency or could it be nothing
In the pictures you see some yellowing and small spots. I don't know if it's Nitrogen deficiency or not because it stays with those two leafs.

Starting to yellow
So I had good growth up until 2 days ago when the one plant started to yellow. I had them going 24 hours a day and I got grow dots mixed in the bottom two thirds of the pots. Could this be light stress? or could it be hungry?

Should I do full flush til runoff is 300ppm?
So, it is obviously a deficiency, which probably caused by a lockout. Will the full flush solve it? Yesterday I fed her a full dose of flowering nutes. Including K. It didn't change much. Lower fan leaves continue to go yellow. Today 3L water, pH:6.2, runoff:0.6l, ppm:1450, Ph6.0

Does that look like an early deficiency?
Hi everyone, what ya thinkin' What kind of deficiency could that be? My bet - potassium. last portion of water was ~6.2 pH I wasn't feeding her nutes for ten days by now. Because previous runoff was ~2000 ppm. I thought would be a good idea to do just water for a while.
