Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.Older leaves have brown/red rusty spots and looks like dying tissue in between the veins.
Burnt tips, and yellowing leaves.
The soil was really dry and my PH meter was 0.4 too high.
I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff.
Runoff was PH: 6.1 EC: 0.8

I think I have nut issues?OK here's today's update, 3/9/22. They are all doing great, they're all standing proud now! I think they needed to dry out a little, more light and needed the extra nuts. What do any of you guys think could've caused these symptoms that my girls are/have shown?

Deficiencies? Brown spots, yellowing and purple stemsWhat is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.

Leaves continue to get yellow and fall off. Plant dying, bud looks okay.Still having issues with my plant. Leaves are getting more and more yellow and 2 have fallen off. Pretty far from harvest still for the leaves to be getting this yellow. Temps in tent are 18-22 c with leds 200w act wattage. Overwatered once but I doubt it would cause this. Ideas?6y ago
