Stumbling Through My First Grow

I dont do dwc or hydros at all, but if it was me in ur position i would just add RO water untill i got the desired ppm. Good luck tho. Stay lit hydrogrowmie.

Yup as soon as they are "sprouted" they are ready for light.. 24-0..18-6...20-4.. You choose the veg schedule.. as long as it's more then 12 hours of light she will not go into flower.. All the light schedules are for is to simulate the changing of the season.. so when you flip to 12-12 in a couple months the plant "feels" that autumn or fall is coming so it flowers..

depends on how fast those stems get woody. I've had some that get quite rigid quickly, and others i could wait a week and still bend it around with no problem -- even if not mainlining, i mean i could shape it to do so had i wanted to given the flexibility. LST is simply shifting apical dominance by manipulating height of node(s). You can do it as you feel necessary. Too much too early can shock a plant.. if it stops growing for a second or two, you were probably too early for that sort of stress.
