First Straight Coco Run - Seedlings Yellowing

[jamesmessenger1]

Hey y’all!

So my seedlings don’t seem to like the plain coco so far lol.

They’re working on their first set of 5 fingered leaves, and the oldest leaves are starting to yellow…

I’m afraid to feed them too much, but if I’m feeding at like 425-450ppm, and they’re still yellowing, maybe I should go heavier…

Just looking for some guidance with seedlings in coco!

Running new millennium secret sauce, but diluted down to 450ppm from 1100ppm.

Thoughts?
Advice?
Experience?

How heavy do you guys feed from seed?

Everything I find is from clone!

Go back to 1100.

How often are you watering the coco? How many times daily?

Do you have perlite mixed in the the coco?
Was it brick coco, or from a bag?
Was the coco pre-buffered and soaked with cal-mag and pH6.0 before use?
How far away are your lights?
What's ur pH in runoff water? - coco should aim for 5.8pH, or at least maintain pH around 5.5-6.1.

EC/PPM for coco. Start with the LOW end of the Recommended EC/PPM Range
