Not light stress, but the beginning of magnesium deficiency. Giving cal/mag will solve this and prevent it from getting too much worse.

Leaves going off quickly at the end of flower.
They have 10 days left ( to finish week 8 of flower) but one of the ladies is loosing leaves and yellowing quickly. Am i doing any harm (to potency) if I let it be for another 10 days? The other two are doing just fine… Thanks!!

Noticing my very bottom leaves are turning yellow. Should I be concerned with this? Any idea of the cause? I haven’t used any nutrients yet.

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!

General question about raising lights.
Gotta question for what most of you are doing to raise your lights? Currently I've just set it static and move as needed. But I'm curious if anyone has a easier method or know of anything made to aid in the raising of the LED light fixtures ?

Light burn?
Is this light burn, or something else? Plants are getting very close to light. Leaves not directly under seem okay, so leads me to believe it's light burn.
