THese are my seedlings germinated May 2nd. Are these growing too slowly?
They do not seem to be doing much in the last week and a half, especially the one on the right.

They are in Rockwool and water. I do not know why I am having so much trouble. 2 other seeds died. The PH on the litmus paper looks about 6.5 or so. THis is really frustrating! Why in the hell will my plants not grow??

They are under 1 4500 lumin 6500K big CLF and 2 2700 Lumin 6500K CLFs.

are they getting enough fresh air?
Click to expand...
I have them in a 20" deep 36" wide and 70" tall steel cabenit. I have a 171 CFM fan pulling air through the top and a 150 CFM fintake filter. I have also been keeping the door open for extra fresh air.

Why are my seedlings all failing!!!!

You need to get them into soil, 15 day old plants should be at the end of the seedling/germination stage something like thisNirvana Northern Lights 14 Days From Seed.jpgthat said they are still alive so the sooner you get them into some soil the better

Here are closer pics.

I want to put them into DWC buckets, not soil. I was under the impression I should wait to put them into the baskets until I could see roots comming through the Rockwool. Should I add nutrients now?

I think there is just to much rock wool I bet there are a couple inches of roots there where you planning to keep in rockwool all way through. If bit I would gentle break the rockwool apart until you see a root then transplant to the dwc

I just started adding my Dyna Grow nutrients to the Rockwool. I PPMed it to 666 PPM it was 130 PPM from the tap. PH is about 6 on the litmus paper.

Definitely don't start with full nutes if you're going to start now starts small and work your way up. Ppm should not be that high in seedlings stage more around 200

PPM for Hanna Chart PPM


Seedlings, Early Sprouts 100 to 250

Early Vegging 300 to 400

Full Vegetation 450 to 700

Early Blooming 750 to 950

Full Mature Blooms 1000 to 1600

Is rock wool your final medium or will you be transplanting to something else also how often have you watered and how much roughly?

I am going to transplant them to a DWC. I have been watering them depending on the weight of the cubes trying not to over or under water them. I started a bit more on the water then tapered it back to let the cubes dry out for a good 4 days until light weight and fairly dry then wattered them today with the 666PPM Dyna Grow "Grow" "Pro-Tect" amd "KLN"
