What's the perfect NPK ratio that u guys used for growing and have the best result? I'm growing my first plants(outdoor) and i just started using 6:6:7, till now i just feed them with seaweed cuz i didn't know nothing about feeding. When it starts to flower i should use something with less Nitrogen, right?

High p bloom foods are a myth, cannabis actually has more need of potassium in flowering.

Balanced ratios like 6-6-7 are good as well, even in flowering regardless what you hear parroted around here.

3-1-2 is a proven ratio seed to harvest for cannabis.

Full hydro may have other requirements for nitrogen however, due to the lack of a nitrogen fixing medium.

OP if I were you I'd stick with that 6-6-7 all the way through to harvest. Get some experience growing healthy plants before you burn and lock the hell out of them dumping useless high p "bloom foods" on them.

N soeso is not very important after stretch.. Correct?!

It's less important after stretch but N is still highly utilized in the flowering process, this is Why leaves tend to yellow in flowering, N is pulled from fans to build flowers. Since we are feeding our plants you want to make sure they have the N they need without having to cannibalize leaves, that just makes total plant efficiency lower . The more healthy leaves you have exposed to light during flowering has a direct effect on flower production.

That's so true. I have found since switch to hydro I had to increase my ph range to over 6, as it looked like they wernt uptaking the the n very well at 5.8.

Does that make sense. I'm quite new to hydro, it seemed to work and slow down the n deficiency I had. :)

Well nitrogen has a pretty flat uptake all through the scale, however in hydro you have to be careful about the type of nitrogen used. Ammonia based nitrogen isn't a good idea, this is why calcium nitrate is used mainly as a nitrogen source in hydro... It doesn't require the nitrogen fixing that Ammonia sources do.

However that being said, magnesium tends to have a hard time with absorption under 6 pH. And can also cause yellowing of fans.

I do, but they have a low npk rating. I also use a bit of calmag and silica

I used different silica proudcts..

I still do but occasionally now not like b4 with everyfeeding..start to become skiptical as I dont notice this mich different with or without.

I think That Ill not gonna buy any more silica when the one I have is finnish.

I used to play with RO and cal/mag.. Not any more as well.. I use just epsom now..
