'rips' on leaves
Leaf damage between the veins only found it on two older leaves, had problems with calcium and magnesium deficiency early on, could this be a symptom of that or what else could it be? Haven't found any pests..

DWC seedling nutrient burn? Please help with diagnosis.
Hi all, my plant pictured here just went through its first root explosion and is now dipping into the water at multiple points. EC = 1.0 and ppm (0.5) = 490. Does this look like nutrient burn? Using Flora series with CaliMagic.

Defoliation
This is my first auto grow, I usually train and defoliate my photoperiodic plants. I thought just lst will be fine for my first autos. I have 3 bushy plants in my 80x80cm tent and the space is limited. I’m wondering if I can still defoliate them in week 4 of flowering.

Hello fellow growers, I noticed some large brown spotting on several of the leaves toward the bottom 1/3rd of the plant. They could be a result of sloppy watering, but I'm not really sure. Any diagnosis would be appreciated. Thanks! 😅

Glossy lower sword leaves surrounding colas
I noticed on some of the lower buds, the small sword like leaves clustering around the buds have gone a bit glossy. Isn't this usually nitrogen related but there's no evidence or much tip burn. Should I lay off the nutes for a Few days?
