Ive read that for flower you want low N and high PK. Ive found 'chempak cactus fertiliser' with a ratio of 8:34:32 would this be a good choice?

Also what strength should i use for foliar feeding? Start out at like 1/8th and move up to 1/2? Im currently still vegging and on 20-20-20 but im syre the same rules apply.

Cheers,
Tom

that cactus probably contains very high levels of trace. if you do get a sucessful crop with it it will probably taste matallic and harsh. just get some jacks classic blossom booster 10-30-20 its formulated for optimal blooms and dense heavy buds. cheap too.

Cannabis is similar to tomato’s in the way it grows and the plant structure but it is a completely separate species and has its own optimal npk levels. Hops would be a better comparison.

Pretty much any fert high in "P", low in "N" and "K", gets the job done for flowering. The Chempak stuff should be fine. Overfertilization is VERY common, so just use common sense and don't over do it. Did you know that if you're in real good soil, you may not even need any supplemental fertilizer?

I'll look into the trace elements in the feed mate. Im in the UK so its very hard for me to get hold of the brands that you guys have access too.

As for my soil, its just standard compost, not sure of the composition.
