15-30-15 is, methinks. Karmaxul will know, he knows everything about ferts.

N is used the most by plants
K is the second most used
P is the least and is easiest to store by the plants

N is tasted the easiest in the smoke which is why growers cut it down to the end of the harvest

Switching numbers can cause stress and plants do not need more P or K in flowering they just process it slightly more. Stress is caused by giving a huge increase and can work against you which is why I recommend leaving the PK the same. That way it is already stored in the plant at the proper level and does not need to balance itself out which is not a overnight process

In veg I would say in whole numbers 16-5-11 cycling the N down or just cutting it off two weeks before harvest to a 8-5-11.

Bloom is really only a additive to the grow formulas which usually lack P. I would not use much of it.

There is also balances between nutes such as the R:S ratio of carbon to N which is best under 20 to 1. Mg combines with N under a 5.8 ph. Calcium works with N and basically there is a big balance. Calcium sulfate is where plants get their sulfur nutrietion.

During flowering the plant needs lots of P, regardless of temperature. 15-30-15, or 5-20-10, or 2-4-3, or something similar, with trace elements should do it.

I don't blame you for seeking further advice. Karmaxul's advice to use low P during flowering goes against every website on the topic.

Karmaxul's advice to use low P during flowering goes against every website on the topic.well karmaxul does give some good advise,but hes not answering the question I asked he's giving me theory's and scientific facts or something,but believe or not he has helped me in many ways and some ways he haven't thats life-get over it
