So ok, start feeding from sprout at 1/4 strength.
When should I start using the 600w light?
Can I use a cfl light too start? If so how long should I use them?
Is maxigro and maxibloom all the nutes I need?
Should I use calmag with maxi series?
here's what I do, adjust accordingly:
i start my seeds with RO with 1mL/gal of dyna gro foliage pro. once they get a decent set of roots poking out of rapid rooter, i transfer to waterfarm. then start at 1mg/gal of Maxi. with RO, EC should be 0.25. then slowly move up. i'm at 2g/gal (0.5EC) now and they just hit their 7th node. i use a scale to be pretty precise.
i don't use maxigro. just foliage pro (high N) and then maxibloom
i don't need cal/mg even with RO but having it on hand is not a bad idea. foliar spray to fix an issue quickly.
for the light, keep it farther up and lower it as the plant gets bigger.
