How do I use powdered veg nutrients

Google the manufacturer yourself and follow their recommendations!

You can apply this as a top dress to your soil and water it in. Typically what you do is put the recommended amount on top of the soil and kind of work it into the top 1” of the soil with your fingers. I suggest going slightly less than the recommended amount because you can always add more later. YouTube has tons of informative videos on top dressing. I’ve watched quite a bit of them when I used to top dress my grows. Hope this helps.

3tablespoons per gallon. Use organic living soil and worm castings for early vegetative stage with 4-4-4. Once in vegetative state transitioning to flower phase, use 4-4-4 and 2-8-4 which will last all the way through your last veg phase and early flowering. then use 50/50 of 2-8-4 and 4-4-4 with bat guano phosphorus in middle of flowering, then flush final week. Hope this helps brother. Make sure to watch your PH, PPM, and calmag deficiencies.
