15gl pots are pretty big, you may not need to water everyday as long as you water till you get 10% runoff. Imo 5gl is all you need to grow 6ft bushes. Your ppm's are pretty high to unless your at the 9th week or so. 80/20 coco perlite is my sweet spot. I grow in fabric pots so theres even more aeration in the root zone. I flush every 4 weeks with micro and enzymes. For final flush i go with molasses. Either way im sure you'll be happy with the results with coco. Best of luck to you.
I agree,,1 5gal is huge,,i pull 2zips per plant in one gal pots,but I'm also into smaller plants,and lots of them.
I do 60/40 perlite,but I'm also feeding 3 times a day w drip emitter set up,or once a day by hand.20% run off cause I was using salts.
At the end of the day,learn what u can but eventually ya gotta find what works for u.personally, I'm going back to making my own soiless organic mix.not cause either is better,just liked it more for my style. I think a good organic mix can grow just as/or almost as fast as coco,less work.but it's all debatable and personal preference.
One love to all ya'll.important thing is that we keep growing,teaching eachother,and moving forward with the hopes of one day growing in our front yards without fear.
