I find using Top max seems t help in keeping the plants healthy and very stinky n sticky but don’t know if it ups the yield or not,,,,,been using top max for many years now after a little while with Boost,,,,stuck with top max as I keep the runs organic,,,,,I am gonna try bcuzz organic booster in the future,,,,use it from week 4 onwards and very small amounts iirc like 1ml per litre,,,,,s2
I think Topmax is just Humic and Fulvic acid, so not a pk/bloom booster, as you say, will keep the plants healthier but wont bump the yields up massively.
