Hi,
I'm agreeing with green on this, more difficult without the pictures for sure.. to know and see where you're at.
VEGETATIVE GROWTH
Nutrient requirements are minimal. Less is most definitely more. Most growers favour a high N feed. An NPK ratio of 3:1:1 during the growth phase. Of course, some strains will respond better with some slight tweaking.
It’s not all about nitrogen, but N levels should always be higher than phosphorus and potassium until bloom. Nitrogen-rich feeds are not required for soil growers as most high-quality cannabis soils contain enough fertiliser for the first 3-4 weeks. Just add water and keep an eye out for nutrient lockouts. Alternatively, Vertafort grow tablets can slow release nutes during vegetative growth. (Which I have, and they work quiet well).
FlOWERING-
Plants transition into flower, nutrient requirements swing in the opposite direction. That means switching to bloom base nutrients and adjusting the NPK ratio. A effective NPK formula is 1-3-2 for early to mid-bloom, followed by 0-3-3 for late bloom. Add a final flush of pure water and/or light flushing solution during the final week for flavour. Then, it’s time to harvest. P & K dictate the quantity and size of bud, respectively.
Tapering off N levels while simultaneously increasing P & K is the primary grower objective. Too much nitrogen late in bloom spoils the sinsemilla. Buds will taste harsh and just won’t smoke as smoothly as a thoroughly-flushed crop. Leave out the N altogether for the final 20-30 days.
Every cannabis strain has its own nuances. This is true when it comes to nutrients and feeding too. Regardless of whether you intend to use organic or chemical fertilisers, you must incrementally increase doses. You simply cannot launch right into full-strength feeds from the get go. Again, Vertafort slow release organic bloom tablets are a viable alternative as they time-release nutes throughout flowering. This is just advice and you're free to do as you wish, but in MY opinion this is what generally works. Good luck
