Hey y’all! I’m currently growing in coco with perlite and I’m 4 weeks into flower. I feed the advanced nutrient micro line…. the whole thing. I’m never going to use it again, to many bottles. My question is how high the ppm should be and when I should measure it. My tap water is 200 and after I add the whole nute line and recharge the ppm is all the way up to 2100. If I’m not mistaken that is way way to high right?
You are pushing the boundaries. Many companies will recommend the 1500ppm range for heavy flower feed, but I also know many growers who swear by the 800ppm range with a few weeks of flower at 1200ppm. I’ve been trying this and have been happy with the results.
Many people only use half the recommended nutrients, and this usually puts your ppm in an appropriate place. I recently went full dose on a run just to see if there was a night and day difference in size and yield….. Didn’t notice one bit. So, like humans, plants will only use what they need, having excessive amounts in the soil doesn’t mean that the plant will eat them all up immediately.
I usually feed the heaviest in week 3-5 of flower, on an 8 week strain.
I guess I should also say – strain dependent.
Spend some time on this website to gain knowlede about growing in coco.
Look up “How to Mix Nutrients” on the site for a feed chart and suggested EC/PPM.

BTW… I feed at 1350 – 1450 from mid bloom until flush. I’ve went much higher with other grows, but I don’t get more. I only increase the chance of burn. I’m surprised at how little amount of nutes these plants really need.
I start with tap water that registers about 250ppm and add Jacks 2 part until it gets to 1300. Any higher, like in the 1450 range burning will come into effect, and any lower for a week or so its like the color will never catch up to lush green.
