Light tops after dark growth (but not clawing)Tops are coming in a bit light on this girl - what gives? I did recently bump up the light intensity a bit but nothing major. Nothing has been amended into the medium in 3 weeks or so to let her fill out the new pot and because she was pretty dark so I didn’t want N-tox. pH 6.5Week 8

Yellowing 1st set of leavesHello,
I'm on Day 11 from seed in Coco/perlite using dry Amendments. My girls are yellowing from centre out and have been stuned a few days now. I'm under the assumption it's over-watering. I've air rated, dropped humidity to 45-50%RH.
Am I on the right path?Week 1

Yellow and fragile leaves 2 weekCouple leaves yellowing and bit curved up. I suggest there can be the options: 1) magnesium deficiency; 2) nitrogen deficiency; 3) Light burn.
For case it is magnesium deficiency I sprayed the leaves with magnesium sulfate (solution - 1g per 1 liter), but it won't help.Leaves. Edges burnt
