Pale green leaves with reddish tips?
MediciGradestarted grow question 5y ago
Stress at the top of the canopy. Is this heat stress, light burn, or a combo? Something else?
Temp in the tent hit 92.5 F at one point, but it's been high 80's in the tent and the leaf surface temp's have been low 80's.
Light was 14 inches at one point but now 24 inches

Looking at your diary your growing in coco and been using very little nutrients. Also your ph is always at 6.5 which is at the high end for coco. If you get your ph closer to 6 and feed some blooming nutrients and cal mag she should bounce back. Try feeding a Ec of 1.2 or 1.4 and make sure you get run off. Go feed, let top inch dry, water, let top inch dry and repeat.

Hey mate, kinda looks like a potassium deficiency to me. But the lighter leaves is making it a little bit harder to diagnose. I think that she has used up her N which isnt a bad thing at this stage, thus making it a little harder to diagnose.

Leaves color changing in flower!!!!what do you think ? deficiency? or is just normal for leaves to become like this after 7 weeks from seed of an autoflower?

Deficiency or leaves turning red/purple due to flowering?Deficiency or natural change due to flowering?
I fed her additional CalMag and PK so I slightly caused nutrient burn. That does not indicate a deficiency normally.
Thank You for any advice!
