yan420answered grow question 8mo ago Looks like classic early coco stuff to me, bit of calmag hunger showing up. Coco loves to strip calcium and magnesium early on, especially without generous runoff.
Your setup looks clean and dialed, doesnβt really scream light stress or environment to me. pH 5.8 is fine for veg, EC 1.2 is on the light side but manageable.
Iβd bump a bit more calmag next feed and make sure youβre getting proper runoff daily. Coco likes to stay fed and flushed, if it dries too much or doesnβt drain well, things lock out fast.
Should bounce back fine once they get what theyβre after. Just my 2 cents without a full diary.
Pretty much the same advice as before, good luck growmie π€πβ€οΈ
