Fox farm isnt full organic but seems to work great for others. There is so much stuff you could do but yield isnt always the nutes problem but genetics or the handler. I hsve a acupolco gold that has troubled me since birth. Still havent mastered that strain as the clones look like shit too.
Im a noob but I do tons of reading and have met a few ppl who I can trust. Myself nor mycomaster would never lie to you.
Whats your goal and budget and alot of ppl could chime in. Alot of intention from myself is going towards teas but right now my temps arent good for tea as my temps are always above 80 at this point but it doesn't worry me. Flowering burst still happen.
Just remember that it isn't so much about mastering a strain. Each bean that you pop of a certain strain will be a different pheno and they'll all have different feeding schedules.
It's more about knowing your deficiencies and feeding only what your plant needs. Feeding more or less than the essentials won't help your plant at all. If you can get that down, growing any strain should be the same. (except when it comes to canopy control and even lighting, that's a different story.
Genetics are the key to growing amazing bud. If you have the basics down and have amazing genetics, you'll get amazing bud.
The reason why a lot of people go organic is not because it's "organic," it's because of the fact that they will barely have to feed the plant (if at all) through their entire cycle.
Also, I just wanted to say that your plants look great. I look forward to seeing your harvest.
