My lux at 12 inch from canopy to fixtures is around 50-60k. Ppms are about 900-1000. Ph is around 5.9 to 6.2. My leaf surface temperature is around 77°f with ambient temp of 79°f - 80°f and a RH of 50-45%. I feed every other watering since the "flush" flush that brought on the yellowing.
The reason behind the deficiency was a double flush. I was under the assumption I was dealing with a lockout and wanted to start fresh. 2 days later bam. They were in serious need of nutes.
I have 6 mars hydro ts1000s. Spaced about 10-12 inches apart. As of now I have 8 plants and the fixtures are about 12-15 inches away from the canopy. I am 4 and a half weeks into flower and I was wondering a few things... Should I move them closer? What should my ambient and leaf surface temps...
So I have a room set up that is 4x6. 6mil diamond mylar on 3 sides 4ft high.. I have 3 mars hydro ts1000s long ways in the room about 6-10inch between the fixtures. I'm trying to fit 6 under them. Would this be enough to flower?
I'm wondering if anyone has tried adding a tiny amount of rooting hormone when watering plants when they are in the seedling stage and early veg? To aid in root development.
Any ideas on what might be going on here anyone? I've been flowering for a few weeks but now my plants leafs are getting badly damaged and the plants are not using up any water at all.
