m0useanswered grow question 3 years ago yes its best to mix in the amendments when your top dressing. I ruff up the top later of the pot and get them in that way. I also water slowly and with a wand that kinda mists it out. if it still hard and clumping together I will stab it with some sticks to help break it up. or add a layer of soil on top of it so its always moist and not drying out and getting chunky.
4-4-4 is great in veg and 4-8-4 should be good in flower. I like to see the potassium and phosphorous reach equal numbers ideally but have seen good grows off of something like what your using. I use Gaia Green "ucann" line and their products are 5-4-5 for grow and 2-7-7 for bloom, Gaia has since discontuniend this lineup for some reason. :( I plan on supplementing with seaweed 0-0-16 to get the extra potassium in flower next run when I go back to 4-4-4 grow & 2-8-4 powerbloom.
Glad to hear you will give them a down time next run, I find it can help solve a lot of little issues and make they shine :D
Cheers,
