You are experiencing progressive potassium deficiency. Light nitrogen and heavy potassium are phosphorus in flowering. Good luck🌱

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)
I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static

brown spots on older leaves
The brown spots are appearing more prominently on the older leaves. Overall, the color of the leaves is rather light green compared to other grow diaries. What could I do to fix the deficiency?

Dark purple areas on leaves — genes or environment/feeding problem?
What the heck is this? Is it just purple genes or a stress/deficiency or a combination of multiple factors? I have checked three visual cannabis plant health guides, and did not find a single issue which looks like this. Maybe a combination of 2 factors, but I'm not convinced 😐

help in Hydro RDWC/DWC
Hello, my plants are now about 4 weeks old. The leaves droop and curl. The spots on the leaves are increasing. Is the PPM value too high? It's 1000ppm tds They grow in an RDWC system with top feed. The top feed is permanently switched on. Can that lead to problems?

Brown/yellow/purple leaves in
This started out as brown spots on big fan leaves and has turned into what you see on the pictures. I've been ignoring the discoloration until I was greeted by some wilted, dead leaves on plant #2 today. I'm not worried at this point, just really want to know what's happening

Could someone help me to identify the issue my plant has?
This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.

First time growing/Need help in late flower
Over the last 9 days my plant has gone from happy and healthy to sugar leaves pointing straight up near the top of plant and drying and curling up on the lower levels. Is this from too much light or did I over feed late in flower? First grow/ no diary. Can I save or do I chop?

Bud rot? Mold?
My plant is a bit problematic ("quick one" Auto from RQS, outdoor balcony grow). I'm a bit worried that I have to throw it out, therefore I would like to ask for your expert opinion. :) 1. Is the "brown stuff" on the top bud "bud-rot"? 2. Are the "more intense white spots" mold?

Browning leaves
My leaves are showing some brown spots 5 days post transplant. I also increased my light from 30% intensity to 80% intensity. I have them 18” away currently. Am I showing signs of light burn? I have since turned the light back down to 50% and I am not on a 18/6 cycle
