Hello!
There are these dark purple patches keep appearing and progressing in the last few days. I'm trying to google and image search, looking at def/excess charts but cannot identify whats going on exactly...
These spots appear only on the UPPER leaves, bottom is green and healthy as before apart from 2 old big leaves at the very bottom that are turning yellow and drying.
Setup is:
- Coco coir
- Feeding 2 times a day, good runoff, good drainage
Tap ~150ppm, 1.5 ml AN cal-mag extra, 4 ml GHE Micro and 8 ml Bloom per gal. Idk the exact PPM because meter broke but I'm sure it is not above 1000.
PH 5.9-6.0
- Temp 23 C (74F)
- RH ~40%
This is an autoflower plant, week 8, around 3 weeks to go.
I keep running same feeding strength for almost 2 weeks. Is this some P K deficiency or lockout?
