First off lets remember that the chart from GH is not set up for what you are trying to grow, the mix is to strong (know from exp). Med hit the nail square on when it was said that nutes to early. Full str nutes should not be used until the 4th set of true leaves appear. From the pic I would say no more than 1/4 str for now. Here is the mix I used and never burned anything Veg 5/5/5 per gal. Flower start 5/2.5/10 this is setup as G/M/B. If you are using any flowering adds like Koolbloom then keep the mix the same and add Koolbloom at 3/4 what package says. If not using an add then after 2nd or 3rd week of flower take bloom to 15.
