Phosphorus def in veg?
Phosphorus deficiency in wk 4 of veg? I noticed a few small discolored blotches on lower leaves 2 days ago and today it is a lot worse! Use flora trio, and 2 other plants in this run are under same conditions with same nutes. Could this be a pH issue? PH has been consistently ~6.

Leaves browning in multiple spots Lower leaves yellowing but have green veins.
One plants leaves are browning in multiple locations. I attempted to diagnose the problem with runoff tests. pH was 6.5 and TDS was around 900ppm, which was expected since they received nutes that day. Despite not spreading to other nearby plants, could it be leaf septoria?

Many or low nutrients?
Hello Growers What could it be? I thought it would be a nutrient deficiency (EC-1.0) so I picked up the nutrients to EC-1.4, but it's getting worse. Do you think they'd have a lot of nutrients?

Brown spots/yellow tips after accidentally breaking a blade
Hi! I accidentally broke an older blade from one of her leaves, and after a couple of days that leaf started getting brownish spots and slightly yellowing tips. Is this normal to happen after a broken blade and will eventually die off? Or is this any sort of deficiency? Thanks !

Brown spots
What is this? It's affecting newer growth, first or second set of fan leaves off thee top of the colas. Also, this drooping, is this stress from the light? This is the center of my tent, and would appear to only affect tallest colas of this plant.

Only single leaf, still cal/mag?
Anyone knows what causes a single leaf to show rust patterns, almost like cal/mag deficiency. Whole plant looks healthy except for this one leaf, literally. DWC, and I use tap water
