Hi
@JR420! If you're talking about the burnt tips, this isn't serious at all, it happens more often than you can imagine. Since this is related to the nutrients you gave last week (or before), I won't change the feeding schedule. She's taller & stronger than last week now, and as mentioned by
@Mrs_Larimar she will need some Nitrogen during the whole veg and even for the preflowering stage. Keep on feeding the way you do, and remember to alternate with plain pH'd water, she should be fine 👍 Hope this will help, keep us up-to-date and happy growing! 👊
