I believe the promix may be mostly peat, but hard to keep up with all the blends. No big deal but may require slightly higher ph. You should probably start feeding lower ppm about the time cots starts to yellow.

What is cots?

Cotyledons sorry. They are the two little round leaves that sprout first.

Usually the 2-3 week mark is a good time to start. Just make sure it’s 1/3 or 1/4 strength since youre in Cocoa. Another good way to judge is the first true leaves, like @Countryboyjvd1971 said. The seed has all the food and nutrients it needs to start up and germinate the plant. But about two to three weeks in you’ll notice those leaves turning yellow. This is a good sign that the plant has run out of the “natural food” it came with. And is needs to be fed!

Ok thanks . I’m using Sensi coco how a&b and Sensi coco bloom a&b so should I still cut recommend amounts?

I would cut at least 1/2. If I’m not mistaken that’s the general rule of thumb for most growers. Just because phenotypes differ so greatly, it’s a good way to make sure you dont burn them off the bat while they’re still young. They’ll tell you if they need more! (Signs of deficiency)

Ok thanks I will post more pics as soon as I get home they are going great

Hey this is Sour diesel auto. I’ve fucked this one, I guess. First time growing in Coco, without soil. In the mix is perlite, Coco& vermiculite. After a certain point it’s leaves start to turn whitish. She’s 15 days.
