I know lower leaves go yellow and drop off but these littluns are only a few weeks old so it doesn't seem right.
They're in Bio Bizz Light, watering twice a week, fed 1/4 dose of of Bio Bizz Grow once a week, 600w HPS, Temps are 75-85, Runoff is Ph 5.8-6.5 and Humidity is too low at 35% RH (working on this though).
First appeared before first feeding, took this as a sign to start the nutes but it has worsened since then, new growth seems good but leaves seem to look less healthy the older they get. Am thinking it's a deficiency of some kind. Any thoughts / diagnoses?
