Hi folks,
I am rather new to growing and a bit worried about my plants (3 amnesia haze and 3 bubblegum). I am using 2x450W LED fixtures in a 4x4 grow tent with 6 plants. The LEDs were about 24" from the plants when the problem started showing up. I am using an oxygen pot ebb&flow hydro system (bottom up bucket full) with coco/Perlite medium, and a nutrient blend from the general hydroponics sample kit (week 2 mix). Ph is 6.4. Nutrient solution ppm is 1000. Using RO water in nutrient blend with cal-mag solution added. The first week after I transplanted the seedlings into the 5 gal coco pots, the plants were doing really well and grew fast. The temps have always been around 72-77F and humidity around 55%. After I changed from the week1 to the week2 nutrient blend, I had a couple days where temp went up to 80F and humidity went down to 35 for one day. After that I started noticing some plants start to curl up at the edges of the leaves, mainly the ones directly under the light. I rotated them out to the side pots thinking this might be heat stress. I then lifted the LEDs up to 28", and made sure temps don't go above 77. I am still seeing these symptoms in the new growth. The new growth seems a little glossy and blistered. I saw a tiny bit of white fuzz on the coco, but not sure if it was just dirt. I saw one fruit fly in the tent. The plant growth seems to have slowed down. It seems to me they are really dry, so I started flooding them with he nutrients once a day instead of once every 3 days. Waiting to see if they get better. Any ideas what I might be doing wrong?
Thank you
