Swompustarted grow question 5 years ago hello! I'm using a prefertilised substrate with NPK 12-14-24 (Plagron lightmix).Which nutrients should I consider to buy next?
Plagron offers a NPK 3-1-3 or 4-2-4 for growing and a 2-2-4 or 3-2-5 for blooming. Beyond brands, what ratio should I look for, for what elements?
Thanks
