For chemicals, I give them Master Blend 4-18-38
15.5-0-0 Calcium Nitrate
Epsom salts.
I give them this, from Start, to Finish. Only things changed is they get a very slow increase in fertilizer, as they get bigger. No switching to other NPK Ratios, when flipped.
In an 8 weeks flowering strain, they may receive a benefit for a slight P-K boost-0-52-34-Mono Potassium Phosphate,in weeks 3-4, and a boost in Epsom salts, in weeks 5-6, and decrease fert 25% in week 5, and another 25%, in week 8. I dont believe in flushing.
I try and keep it as simple, as possible, while trying to strictly adhere to some basic principles. Like Air Flow. One f my biggest concerns, is fresh air exchange. Not just blowing inside air around, and it can be a challenge. Lots of strong light. Feed them, enough to be healthy, and no more. Learn how to properly Water plants.
If a person can just be able to have really good air exchange/ Learn how to feed and water properly, supply them with strong light, and use a good base medium, thats all it takes. Air/Co2-Exchange. When/What to feed/water Properly-Strong Light. Good Medium. DONE.
