I have read the directions for Dyna-Gro Bloom, and it is telling me to fertilize every watering, but won't that burn that plant? Or will it be safe? View attachment 4437813
If you've never used Bloom by DG before, I would rethink. 3-12-6 is way too much P for cannabis.
Get a bottle of DG Foliage Pro instead and use it start to finish. 3-1-2 is better ratio.
And I always supplement with Mg via Epsom salt. I believe it's only 0.5% Mg
