Quoted for autos.....about 3 weeks after light flip to start PK for flowering photos sounds right to me.
Sorry reb...its not quite what i meant to say. What i meant, is its easy to overdue nitrogen especially in flower, while simultaneously falling behind in P, K and Calcium.
Haha
Yeah the indoor autos i run are in 7" standard pots(1.5gallons). I primarily use them to give me lots of variety, but i did notice that overall space yields are superior in my setup versus less plants in 3 gallon containers.
