Yeah that’s very funny that I spent 9 weeks to only get 1 gram. This plant had some issues drooping leaves and yellowing and I seasoned all that with adding coffee ground that also completely ruined my another plant even though some growers benefit from it, me personally will never ever use it again as a fertiliser. So I couldn’t do flushing and honestly didn’t even fully wait for all hairs to go brown and shit. The next time will definitely do better and it’s also the strain itself very small also now I realise to never transplant it from the medium pot to a bigger it can only go from small one to the big otherwise the whole growing medium fall out my hands with the whooolee root system crashing and destroying itself. Also considering to try a different grow medium because soil is a real headache.
You use coffee for fertilizer during the veggie side and don’t use light roast anything way to acidic use a dark roast so it won’t floor your ph levels, I’ve had good experiences with it, don’t know exactly when you added it or if you noticed the level it got to. Just remember no light coffee it’s bad only use a teaspoon for each plant anything more will burn it and I would only do that every two-three weeks. If you got questions or concerns send me a message I’ll try to help dial things in with you.
