This is some sort of excess / burn, correct? First living soil grow
Hey all, first living soil grow here. I am 4.5 weeks from seed. Over the past weekish i’ve noticed some new growth looking off. Almost like mag def, but it’s on newer leaves. So I’m just making sure my assumptions are correct that this is some sort of nutrient excess possibly causing mag lockout.. But could possibly have been too high PPFD. As they’ve grown closer to the light some spots were nearly 700 PPFD on 18/6. Just lowered to it 580-630.
Before planting I top dressed each earthbox with:
1/4 c craft blend
3.5 c buildaflower
1/8 c gnarly barley
1/4 c insect frass
1/8 c kashi gold
Been using microbe complete, WDG3000, Q20
About a week ago I hit the earthboxes with ~1/3 the recommended dose of Big 6 Micronutrients
Setup: 2 Earthboxes in a 2.5x4.5
Light: HLG Diablo 350R
Soil: BAS 3.0 (1.5 bags per earthbox)
VPD: 0.9
I see some people say 3.0 has enough nutes to get you through an entire run depending on container size. And I see others saying to top dress new 3.0.
I’m gearing up to flip them in the next week or two but want to hold off if this is gonna cause issues down the road. But I also don’t want them over growing their containers and have to play catch up all flower. Either going to top dress then flip, or top dress after the inital stretch. Any advice is appreciated, thanks!
