Dr Nodes in coco is also futile
but you can check out Nitrozime like i stated above I plan on using it in my scrog. I don't think it ''attacks'' the plants like bushmaster does but it does promote more inter nodes, bushiness and SLOW or decrease vertical growth. Like I said its just a less aggressive organic form of BM
You can foliar feed BM and i've heard it has been immensely successful but they where trading of feeding it for one week then spraying it 3 weeks in a row then feeding again. I'd imagine it wouldn't do any damage to do that in reverse? just foliar spray once every 3-4 feedings
But I dont know how knowledgeable your local grow store is but ask them if not just get the nitrozime and walk out i'll walk you through the rest lol
I havent used phosphorload I heard it does the same thing though I cant speak from personal experience. I'm in soil but dabble in coco too
