Gorilla Zkittlez Closet Grow

Start of week 4, It doesnt look bad, but why arent the leaves standing up, it seems like its growing ok but theres something to improve because its growing kinda slow imo. If you have any clues feel free to share! im changing my nudes to the growing schedule of Floramato GHE and i adjusted the lights, not to shine direct on the plants, i think its too much for now. Day 25: Since i have changed the light direction, the leaves are getting alot bigger. conclusion : the lights are too much for the little ones. Also my ph meter was showing wrong results, manufacturer is sending me a new ph pen because its not working properly, so i have kinda been guessing the ph, I can tell because some leaves are turning to one side. Day 28: I was afraid to burn my plants with the growing schedule, since i doubled my ec by doing that, but still no burn. Stems are getting big, I'm just not sure if i bought the right light for this setup, they only get indirect light because the leaves stay so small when i put the lights directly above the plants
