Nitrogen (N)
Nitrate - Ammonium is found in both inorganic and organic forms in the plant, and combines with carbon, hydrogen, oxygen and sometimes sulfur to form amino acids, amino enzymes, nucleic acids, chlorophyll, alkaloids, and purine bases. Nitrogen rates high as molecular weight proteins in plant tissue.
Plants need lots of N during vegging, but it's easy to overdo it. Added too much? Flush the soil with plain water. Soluble nitrogen (especially nitrate) is the form that's the most quickly available to the roots, while insoluble N (like urea) first needs to be broken down by microbes in the soil before the roots can absorb it. Avoid excessive ammonium nitrogen, which can interfere with other nutrients.
Too much N delays flowering. Plants should be allowed to become N-deficient late in flowering for best flavor.
Nitrogen is mainly used for stem and leaf growth i believe. I use my growth nutes through the 1-2 weeks of flower, then i start to taper my N off.
Ive been doing some reading about using more potassium later in flower rather than P. H&G new shooting powder is 9-20 P,K and is supposed to be used in late flowering. I am also using MOAB in week 5 and maybe 6.
I am also running two other brands of nutes, and do the samething, and using MOAB and Krazy Kelp with them. Krazy Kelp is 1-0-17 and plan on using the MOAB during week 5 and maybe 6, then using the Krazy Kelp week 7 and 8 depending on harvest time. KK doesnt have the P that Shooting Powder does, but itll help confirm if higher K later in flower is better than P. Which is what alot of bloom boosters come with.
