yan402answered grow question 9 days 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, doesn’t 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.
I’d bump a bit more calmag next feed and make sure you’re getting proper runoff daily. Coco likes to stay fed and flushed, if it dries too much or doesn’t drain well, things lock out fast.
Should bounce back fine once they get what they’re after. Just my 2 cents without a full diary.
Pretty much the same advice as before, good luck growmie 🤞🍀❤️
