nutrient levels

I do organics. But I aim to have nitrogen or grow formulations still being used along with bloom for the first 3 weeks after 12/12. Nitrogen for a proper stretch before you cut it off. Then make sure you're hitting her with cal mag at weeks 4 and 5. Calcium builds cell walls which is what your plants doing at weeks 4 and 5 by building buds Then the last weeks you'll want to push pk mostly. Normally with more potassium than phosphorus Hope this helps. Check out a pH absorption chart and you can customize it even more

What are you growing in? Are you measuring individual Elements?
