IMAG0362.jpgIMAG0359.jpg Here is little background for everyone. I got 6 purple wrecks that I have veg for a month and now I'm 2 weeks into flowering. They have been getting there nutes from a ocean forest/light warrior mix. It's been 3 weeks since I repotted them. I got some bio-grow, bio-bloom, and ALG-A-MIC. I started feeding them 2ml per liter bloom, 1ml grow, 1ml ALG which reads around 250ppm does this sound right or should I go higher?
