Slow seedlings

Have two red poison seedlings that almost took a week to pop instead of the usual three to four days. Normal for this strain? They also seem to be barely growing, everything is dialed in.


Coco coir/perlite= 80/20
Nutes = 200 ppm
temp= 78-82F

is this your first run in coco? one thing i have noticed is starting in coco is usually a slow first 2-2 1/2 weeks.. and then they really take off.

how far in are you? if you got everything dialed in i would just wait it out.. by two weeks though im feeding about 3/4 strength GH 6/9, and its usually around that time they take off for me.

If the seeds are older or not stored properly they can take longer to germ and have less vigor. Is your 200 ppm on top of tap water? With coco I'm using RO and starting seeds in around 450 ppm / 0.9 EC which is mostly calmag with some additives and grow nutes. Coco seems to steal the ions away from the seedlings and stunt growth with weaker solutions.

Ive been doing coco for a good while now. I planted some extra seeds next to the ones i bought just in case they dont make it. Its been a week and a half and the white dwarf have exploded and are already throwing out a second set of leaves. Red poison is just now breaking through, they are taking forever to open up.

thats good news. so you never usually have slow starts in coco? maybe im doing something wrong lol.

i have some at 3 weeks now, it was only after the 2 week mark they blew up.
