Nutrients If I'm using GH Micro & Bloom, could I just add more Bloom instead of buying a PK booster?

[Bantersaurus]

I've been using Lucas' formula (6 mL micro/9 mL bloom), but I noticed that it was only 1440 EC. With Mega Crop, I could get up to 1600. Could I just use more Bloom to cover the gap and replace a PK booster since it's 0 - 5 - 4?

I'm in coco, if that matters.

How much of the 1440 EC comes from your water? It is virtually impossible to answer the question because we do not know the elemental PPMs (not EC) of the products. This chart shows the range for each element in elemental PPM. If you keep each of these in range the plant will be happy.



Less is better assuming balance.

My water's around 5 - 6 ppm. I guess my question was more whether their PK booster (maxibloom or something) is necessary when Bloom seems to already be PK. You may not know the elemental composition of GH's line, but growers with experience should know what EC to shoot for and what ratios to maintain with Bloom/Micro - they're the ones this question's for.

Yes, just adjusting bloom ratios can increase your PK like a supplemental product.

Supplements are mostly snake oil.

That said, cannabis doesn't really NEED a PK boost, especially not in coco.
