The dark color is looking like ph imbalance... intervein chlorosis looking like start of magnesium deficiency... depending on what u are feeding mabey ph related as well. Make sure to check ph. If ur not feeding magnesium.. feed some. Happy growing and stay lit fam.

Gray leaves on buds with a massive concentration of trichomes. What is it?No clue what this is. Light gray leaves, tons of trichomes. I'm a bit confused here. Should I just cut the buds that look like this to be safe? Or is this normal?

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static
