Stumped as to what’s going on

What are your Temps like? LED likes 83 to 85 degrees F throughout the grow. Sorry if this has already been addressed. If your VPD is in range, some Epsom salts should do wonders (as several others have suggested).

Temps are 80 during day and humidity is at 65 so just about right for vpd. I switched to flower so we shall see

I went through something that looked very similar with the striping, on my first grow, right around the same time. I ended up adding cal mag and it helped the issue.
