If you had leaves wet under light, possibly lightburn.

I'd guess a calcium and/or magnesium deficiency

Nutrient Burn, Leaf Septoria, Nutrient Deficiency? Or something else?
I have been having issues with the Purple Haze. I've tried adjusting the Temperatures, adding additional Cal-Mag, changing lumen intensity etc. I believe this may be nutrient burn? Added an old image of leaf before mainlining, the plant is 1 week old after mainlining was done.

Going coco with coco coir!
How often should coco be watered? Some people say every day some people say wait till coco dries up a bit, then water? Been watering every 3-4 days and ive had all kinds of deficiencies. Not sure if it’s from the amount of nutes I use or I just don’t water often ? going coconuts

Lower leaves too pale or yellowing?
I am noticing the lower leaves of my Royal Critical Automatic to be much more pale green than the top of the plant. Is this a nutrient/light/watering/lst stress problem if at all? First Grow. Started balcony, moved to tent D23. SF-1000 light, 100% at ~ 55cm from canopy.

What is this leaf showing?
Anybody knows what is going on with this plant? My first guess was nitrogen toxicity because of the leaves clawing down a week ago, but I am not fully sure anymore with how the leaves are looking now.

Why my plant is in shock i fixed the ph of watering .I suspect of this reasons:Heat wave/changing phase to flowering / nutrient locked/ over watering/. In
I lowered the ph of watering from 6.8 to 6.0 but this plant is still is shock and wont grow like others. Could it be a sign of changing phase from veg to bloom ? 3 weeks ago my first plant went to flowering and did the same color fading. Now that plant has good color

Yellowing
Hi! It looks like my grandaddy purple is starting to yellow, in my last week of veg (7). Could it be caused by too small of a pot (3gallons), this is my 4th grow, first time growing only one plant using scrog. Maybe an upgraded pot before I flower? Thanks!
