Leaves turning yellow/pointing up, stem turning purple
Having a problem with one of them.. all the leaves have gone very yellow and are pointing upwards. The stem is also very purple now. Any ideas what this could be? Other than a feeding of bud candy and watering here and there it hasn’t gotten any other feeding. Thanks!

Fan leaf deficiencies during flower. To cut or not to cut?
Day 85 Update: G13 has a ton of fan leaves turning fast. Pretty sure it's a PH issue. Should I wait until they're dead to trim them off or get rid of every fan leaf that is affected more than 50 percent of the leaf?

Yellow leaves near the harvest
This would be my last week of fertilizer watering. And the plant has the leaves turned to the side and with yellow spots. Sign of lack of zinc? I would start making the flush from Friday, is it recommended to start now? In about 2 weeks I will harvest (I tried to water today)

The leaves are wierd shaped, but growing fast
Hi everyone! Please tell me, is it a consequence of leaf scorch with light, or incorrect watering, or I was very in vain in the beginning added root booster? The big question is, is it worth waiting for a potential recovery?There's nothing like it at google

Brown yellow leaves?
Can anyone help me? I had this issue with my last early Miss and thought it was a cal mag deficiency. I tried to adjust it last time during flower but it didn’t help. I really only notice it on one of them so far but I would like to fix the problem sooner than later.

Spots and dry leaves.
Help! I don't know what's happening to my Q1. There are spots on the leaves and some of the leaves are really dry. I didn't do the defoliation and i didn't LST so the plant is just going all natural. I feed her nuts from ATAI.

Troubled seedlings
Is this nutrient burn? Had what looked like a lack of nitrogen early on, lowest leaves were healthy then quickly went yellow and worked up. Now have fed nutes at 0.7EC (tap water left for 24hrs to 0.28EC) so fed under 0.5. Bio-grow 0.5ml/l bio-heaven 1ml calmag 0.25. Thanks

Leaf problem and purple stems
Hi, I have a problem with my auto. I have purple stems and problems with the leaves. The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem. Is it a nitrogen deficiency ? Thank you for the answer

Nute burn (Added nuts to supersoil)
So, I added unnecessary nutrients to my super soil and end up with nute burn, I Flushed until ppm was 1100 it was over 6000, and since i've been dealing with yellowing and curling leafs, brown spots and well it's all going down so quick. Any idea how to fix this. I'm lost.
