Leaves yellowing and burning mid flower
Air exchange, pH, nutes, and water should be good. Could my 230 watt on 100% be too much for her? Does she need more humidity? What causes crispy leaves?

I have tried to figure out what this could be without much luck... it seems that my leaves are having a slightly yellow tint to them under the grow light. Under normal light it seems ok, what could this be? Overwatering I am guessing but not sure.. Any help would be appreciated

Leave colors on 3 week old clones blackberry Kush in Coco coir and a jiffy disk
Sudden yellowing and discoloration of a e or 4 week cutting. I water it when I see the Coco getting a little dry. I make sure there is at least 20% of run off water. I watered with pH corrected water to pH of 6. I also add a small amount of canna bioryzotonic for their roots.

Yellow parts on very young leaves
She's only 2 weeks old and some leaves started yellowing. Should I be concerned or it's a normal thing? Watered her a few times with distilled water (no nutes). Also, there is about 30-40cm distance between the plant and the light (SF1000, put on ~50 power)

Yellow Borders and Curling inwards slightly?
Some of the new leaves on 3 plants have got slight yellow borders and are curling inward slightly (please see third pic in this week) - is this due to over watering, nutes? or something to do with humidity? Many thanks!
