Hey all

New to growing and am starting to see issues with my seedlings.

Running DWC at 5.8 ph in 1” rockwool cubes.

Started them from seed in a dome. Seemed great. Since there are no nutes in rockwool, added 150 ppm calmag. 2 days later started seeing slight yellowing where newer growth was. Now starting to see spots appear. Growth seems slowed.

Not sure if it’s nute burn or a deficiency as I thought nute burn is at the leaf tip.

I attached a picture. This is day 8 since first sprout.

Suggestions welcome.

Cheers.

I should add I’m growing under a Feit 2’ 19W Led full spectrum grow light at about a distance of 8” from the top of the plant.

Temp is 23 degrees.

I moved from the dome to dwc as 6-7 roots were coming out of the bottom of the rockwool at about 1.5 cm and exposed to light.

Strain is Royal Gorilla

Using General Hydroponics trio with GH Calmag and super thrive.

Cheers.
