seedlings of white widow, ice and crystal are about a week and a half old.
growing in coco medium
under 24/7 600HPS lights
watered 2min every 4 hours
PH is regulated between 5.6 and 6.2
EC (using GHE florIMG_1967.JPGa series on RO water) was 0.6

plant leaves started to go bright green...moved from the outside of the leaf to the insidIMG_1968.JPGe...

looks like your feeding them with a real light food, I would increase your nute intake cause it looks like its lacking nitrogen. Also you might wanna check you waters ph

waters ph should be around 6.3-7.0 which reverse osmosis is 7.0 which should be fine and your ppm with a veg food should be 800-1000ppm so looks like you just need to feed them a little more

but when I raised nuts they reacted badly and leaves tips started to burn...
should I still raise nuts?

how much time will it take for me to know if I raised by enough?

btw. I'm growing soiless on coco...so ph should be 5.5-6.5 no?
