Budlets seem awfully little!!!! Plz help

Hi guys I've got three northern light autos in the corner here and as you see all the budlets are very tiny I'm growing in Coco coir I'm using Maxi Bloom and a Cal mag supplement under 2 600 w Vander life LED 110 w actual draw.. in a 2 x 4 setup I'm so glad I could finally get registered and get some advice..the other one is glookies power plant mystery seed blueberry and gelato OG eight plants in a 2 by 4 I know that seems a little crowded. Any advice or tips are all welcome all female seeds from different breeders but all through seedsman.

Realistically you should have about 50w/sqft with blurples, you have about half that. I would look into quantum boards.

Otherwise, your plants look healthy.

my lights recommend that I keep them 11in away but when I do they show signs of heat stress but since I have two of them in a 2x4 don't you think that might be enough

And I've had a few successful grows with these lights although I believe my rookie mistakes caused my purple Moroccans to hermaphrodite have to have any experience with viparspectra
