Looks like potassium to me. Do not raise your nitrogen level in process. Your well fed there. Always be aware of run off ph and tds or ec.

Yellowing and lightening of leavesMy back-left plant started to slightly yellow on me from the bottom up. Front-left is also lighter than the rest. Is this a feeding issue? Do they need more nitrogen or did I overwater them? Appreciate your answers :)

Fatal ovewatering? Will she survive?Ugh! One of my two plants Is dying. I suspect overwatering associated with some other issue I can't spot properly. 58 days flowering. It was my first flushing session, not a good start.
Her sister has no problem. Poked holes in the dirt, raised temp, maxed the fans. What else?

help in Hydro RDWC/DWCHello, 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?

Yellow sugar leavesI am waiting for a low-THC strain to develop amber trichomes and I found two buds with these yellow sugar leaves. There is no bud rot, should I wait longer to harvest? Also, do CBD strains develop amber trichomes, or should I harvest now? Additional details available in growdiary

Brown/yellow/purple leaves inThis 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
