I'm sure this has been asked over and over but kinda like finding my socks I can't lol. Just started a tray of White Russian and they germed for 2 days and then into the rockwool and balls. The light has been on for 18 hrs for 4 days and I turned it down to 12 this morning, When should I switch to flower nutes, I am using sensi perfect PH I think but may switch. My very first grow of this strain stretched a massive amount and am trying to keep this one under control lol. Thanks for any help!! Oh and just one more question!!! lol. I have a tray of White Domina that is in its 4th week of flower and my TDS is 607 @ .5 and it rises by about 5 a day. Does that mean I should lower the amount of nutes added? It seems kinda low after reading guys are at like a 1000 at 4 weeks. PH is a steady 5.8 BTW.
