I have been vegging now for about two months (this is my first grow), the leaves only at the top are yellowing on the outside and have purple spotting. I used Royal gold king mix, kelp, crab, alfalfa, and neem meal in my 3 gal pots. Along with rock dust and top dressing. This has been happening now for almost two weeks. I already did a foiler spray with mag and flushed. I feed them yesterday because I knew it was time for a feeding. Should I just flip to flower and just get it over with so I can start my next crop or should I figure out how to fix this. The seeds I'm using came from a strain I had and I was lucking to get three girls. Could anyone help me out here? I'm using mars sp250 in a 4x4.
