Whats the best bloom boost to use with soil for hard buds.

[markmr3]

Hi all, I grow in 15lts pots of soil and its a mix of 50% soil, 35% perlite and 15%clay pebbles for more airation. I only use water on the top of the plants so they don't get nute lock and I feed the plants in saucers at the bottom. Ive tried Canna then Bloombastic growing Green poison, Plant Magic then flower bomb growing Dame Clara and latest was all the dutch pro nutes inc explode growing Gorilla Glue. But I seem to get the same results all the time where the buds don't go tight and hard. Plenty sticky but not heavy.. Growing on 2 x 600w MH, flowering on 2 x 600w turned up to 660w Omega sodium. 2 x 4in cold intake and 2 x 6in extractors. I have grown super autos and had nice firm buds, ive even tried exfoliating and even bending / tying branches down. But all I get is the same results. I just don't know what to try next. Any help please

Tiger Bloom works well.

Ok thanks, what boost nute would you recommend with that.

in late flower you want a good p/k booster only
since your in soil is this an organic grow?? if it's not organic you might wanna go coco

plants genetic play a large roll with bud density, it's more than just food & lighting,
anything heavily indica leaning will be more tightly packed together than a sativa leaning girl

Most percy growers on here dont worry about their bud being rock hard. You can get PGRs to help with that but just a plain simple PK product from canna or the like will give you nice firm buds.

Good dialled in environment and steady feed and good light and youre golden

2x600w is a lot of light: how bigs the space? And how many plants?

Super soil dude . This is grown in soil without fertilizer . Sardine meal . With kelp and crab and worm shit in 7 gallon grow bags under 600w .
Nothing else . I pushed the soil recipe just to say it was borderline Toxic as a test .

But fair warning . DO NOT USE THIS SOIL FOR AUTOS
