Green Crack White Spots

Hello everyone,

I have a puzzle; This is Green Crack with a problem that does not appear to be hurting the plant and is not spider mites. What is it? Do you know? Help, my local hydro store has never seen it before!

If it is not hurting the plant now, it probably will as it does denote some kind of problem.
as a side note, a lot of the hydro store people don't even grow--their main job is to be salespeople.

We do need more info about your grow--room size, light type and size, size of pots, exactly what they are planted in, what do you feed them, how much, how often, what is your pH, temps, RH, how old are they, from seed or clone. etc, etc. The more we know the more we can help you. But without more info it would just be a stab in the dark.

I would say it is some kind of micro element deficiency, most of the times, ph is suspect in hydro, but then again, all we know is that you went to a hydro store, but dont even know if you grow hydro and what else, more info needed to diagnose the plant's problem, cheers :vap-Bong_smoker:
