i gave them nutes that was recommended every week but i gave 2 or 3 times in a row. but i already stoped it i give only cal-mag water with a ph of 5,8 the perlite is brown i think because i flooded too mutch water so the dirt came out. i have heart of flush the coco on the beginning before usage, i did not. the temps was 28-30 celzius however i added a fan now so it's 23-25. i also started with 2700k cfls but seen 6500k in the store so i replaced them , maybe the change did not good for the plant too ?
so flush it and give it just pure 5,8ph water ? hmm but coco needs allways some mag-cal nutes or ?the cfl light spectrum change would not cause that problem. those previous temps were too high, but should now be good at 23-25 C. that plant is really too young to be given a lot of nutes, if any. there should be a good amount of nutes in the soil for a plant that size. might want to flush it out real good, then give it a week or so to see what happens.
in other words, we'd love to help, but we aren't here to hold your hand. we help those who help themselves, and you'd have a much better understanding with a few hours of reading...when I wished to learn to hew timbers by hand, I bought a book. I read the book. I read it again. I watched videos of guys hewing timbers. I did Google searches for "what is the best Swedish broadaxe?" and, "how to sharpen an adz."
then............I went out and bought the tools, and began the hands-on learning process...............
I like to help new growers that are willing to do the work; all of it. I will teach someone, from the ground up........for Bitcoin, or bullion. nasty, dirty, greasy Mexican meals, and a burlap bag, in grow-room, to sleep on, included.
hahahaNext time use coco designed for growing dope when indoor. Im not sure what your using but it looks like its growing out of a chocolate crackle.
