Exactly! Do it in small steps, once you see a little bit of tip burn back off. People can tell you "safe" ppms but everybody's garden is different the only way to really know is to find out for yourself.
the plant ppm is 800 and about 20 % of the leaves have very minor tip burn. I am thinking 770 next cycle will be better. Also about 1 inch of just 1 leaf is turning lighter shades of green. Is that a deficiency or due to the nutes?
ok a Mg deficiency is easy to fix.My water jumps up from a 5.4ish to around a 6.0 alot. Its been 3 weeks since the pants have been in hyro, Should I flush them?
