yan402answered grow question 2mo ago Hey growmie,looks like early Calcium Magnesium deficiency to me, classic stuff when the plant starts drinking more in early flower. It usually happens if the substrate stayed too wet for too long in veg or if the nutrients were a bit on the light side.
Nothing dramatic though, just check your pH aim 6.2-6.5 in soil and maybe give a little CalMag boost in the next feed. Let the top layer dry properly between waterings so the roots can breathe better.
Leaves already damaged won’t recover, so focus on the new growth, that’s what matters. She looks like she’ll finish fine once the rootzone is stable again.
Good luck growmie 🤞🍀❤️
