1 out of 4 plants really looks sick. The others are showing some of the same symptoms but not as much as 1. Plants have been in flower cycle for approx. 9 days. have not shown sex yet.
Feeding cycle: 4 times for 5 minutes for 12 hour cycle
Fill and Drain system
Ph approx. 6.0 (using liquid drops test)
ppm 1540
cf 22
EC 2.2
Any help would be greatfully appreciated.
could be wrong, but it looks like a magnesium deficiancy. some would say sulfer. sulpher? but those 2 some together in magnesium sulfide. its been a while since ive had that problem, but i too am 2 weeks into flower. and that normally happens around that time. the plant is needing more blossom nutes. I would feed them some 0-0-7 or 0-0-3. beastie blooms is like 0-50-30, but i dont feed it that till late in the flower cycle.weeks 8-9-10.
watering too much. slight nute burn. should only be on 3X water cycle none during lights out. bring ppm's down to 1000 & adjust water schedule accordingly. r
What is the Ph? It could also be a nutrient inmobil as well where the Ph is out of range for the cycle of life thus the required nutrient is present but not available to the plant.
What type of water are you using?
What nutrients are you giving them at this cycle?
