Hi another attempt at the +speeds from sweet seeds.

I’ve been noticing dark green leafs also curling at the tips and have yellow tips aswell I was think nitrogen toxic but I have been flushing for 6 days now. Any advice would be great
Thanks in advance

Too much light, too strong a wind, too high temperatures, not enough humidity, and root problems can do this.

Nitrogen problems show up at the bottom of the plant first. The tips turn down, and the edges of the leaf blades turn up forming a taco like structure for nitrogen toxicity.
