Ok guys, I need some help, I have 50 blue bream clones that i transplanted a week ago into 6inch rockwool cubes, I use the general hydroponics feeding chart, and I use the flora duo reccirculating, I went off week one veg, which calls for 2.5 mililiters per gallon, I went ahead and used 3.5, but the next week calls for 5 per gallon, anyways, long story short my plants have purple stems and stalks, and color of the plant is a weak green/yellow looks unhealthy, Im almost 100% sure its Cal Mag, do I just need to give it more Cal Mag? I got alot of Cal Mag to use, lol. Help, need HELP!
