Today I spotted small brown spots on one of the leafs of the G13xPU. I am worried because the plant is so small. I have not gave it any water yet. You guys have any ideas. Are the lights too close? Too much N in the soil? Needs nutes? Not enough air in the soil (I made a mistake of not adding any perlite)?
The other plant looks healthy even-though its smaller, with darker green leafs and a hint of purple.
Day 20. Watered both for the first time few days with 1/2 gallon each of Grow Big (1 1/4 tsp per gallon). Both exploded in growth the next day. Both also show a bit of nute burn, nothing too major as of yet. The bigger plant (G13) has more affected leaves than the smaller one. My guess is the root mass, it also drank all the water faster, and had roots to the bottom of this 12'' by 12'' pot on day 9!!! I really hope its a girl, but is showing what looks like very tiny balls. I hope not!
