Is 5.0-3.0-8.0 a good NPK??

Just need to no if this is an ok NPK and cud it be used in flowering?

Use something that has a higher P rating.. Like 10-60-10 at 1/2 strength,then increase dose as flowering increases.

That is only an example. You'll be safe with that,cause I use 2-3-5 Pure Blend Pro Bloom.

IMO Fine for the first couple weeks of flower, after that you want something with a lower N content.

GG mentions 2-3-5 <--- You want the lowest number to be the N :thumbsup:

If the 5-3-8 is all you have, use it. You just have to make extra sure to flush before harvest and let the plant use up its stash. N tastes $hitty. :(

Jacks Classic "Blossom Booster" is a good, cheap, flower fertilizer, 10-30-20. They sell that stuff damn near everywhere.
