I don't see anything that is black... dark green, yes - and to my eyes, it looks very healthy! Give her time and patience... I think she'll be fine! Good luck!

Leaves burn
Hi! Is this nutes burn? Damage is on the upper/middle part of the canopy on very few leaves, but many more have black tips. I’m puzzled because during veg I was feeding the plant higher ppm than now and never had a problem!

Seeing some top bud leaf discoloration
Starting to see small dark/black discolorations on the leaves. Since I don't know the genetics, I can't tell if it's prone to dark leaves. Could it be signs of anything else? Note: Started watering only using TopMax and ActiVera because of some possible Nitrogen toxicity

Yellowing to slight grey leaves
What's the cause of the older yellowing leaves with some grey and the slow spread to the newer growth? I'm between pH problems and or deficiency but not too sure.

What's Happening to my Glookies? Lower Growth Yellowing with Grey/Light Brown Spots.
Yellowing with grey/light brown spots occurring on the Glookies plants (starting from the tip of the leaf). I believe it may be due to the Fox Farm Ocean Forest soil mix but any advice or input on what is possibly happening is greatly appreciated. Fingers also fused together.

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

Bud leaves turned black
Top leaves turned brown overnight, That day I did come home to a disturbing temp off 31oC . It’s the black Mini leaves in buds that are worrying me more. lights came on accidentally for two hours so gave her 16hrs dark and back to 12/12 This may have contributed.

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?
