Hey Tik, I looked at my notes and I started 3 seeds on the 22nd of Oct, and I flipped the lights on the 4th of December, so I'm a few days short of my 5th week of flower. I think you'll be ok with the nutes, just keep an eye on things..and as far as watering, you can water a lot..I mean a lot of water, but the time in between is what matters the most. Let them get pretty dry before the next feeding or watering. I've seen some guys that actually dunk their plants under water until bubbles stop coming up, and then let them drain. Just use your finger or a lot of people judge by how light their container gets when dry, compared to wet. You'll get it
