Is this a Deficiency or Normal Flowering.
Flower 4 weeks. I have noticed thru flower approx 5 - 10 leaves/week which eventually brown, shrivel up, and fall off. Leaves seem dark and the stems are slightly reddish purple but potassium test on soil shows high potassium. Some burnt tips and claw down on upper leaves. PH6.0

What is this deficiency?
They started off with some brown spots and progressed. Is this phosphorus? I have been feeding with .5-1ml of dyna grow bloom and 2ml of cal mag per gallon watering at about 6.3-4 ph. But i recalibrated my ph pen and did one water since.

Week 2: One of the plants still doesn't look good + other beginner questions :)
Second week and one of the plants has weird spots + leaves curled. Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea. Also, when should I start feeding the plants? And how much water do I need at this point? 😥

Yellowing Too Fast Or Natural?
I'm roughly 2-3 weeks into flower. Over the last week, I've noticed more yellow leaves than normal. Majority are bigger, older fan leaves but some are moving up the plants. New growths are a nice green and buds look healthy. Am I under feeding or overreacting?

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?

Yellow Cotyledons?
NLxBB was born with yellow cotyledons. The shell was stuck after sprouting so I had to help remove it. Took around 2 days before I saw them barely open with new growth. The new growth is green and seems healthy. Is there any reason why this is happening?

Why are my plants leaves so bright green/yellow?
Wondering if anyone knows why the plants might be looking as light green as they are? We are running a purely organic grow and have not added nutrients beyond the super soil mixture. Wondering if anyone has any tips or suggestions, thanks!
