Hay bud, look, having yellowing of leaves at the top and green growth underneath. Means, it just screams a nutrient Lockout issue. If you provide more information about the plant and conditions of it, then more Peeps can help you out with your situation.

It’s a northern lights autoflower I just recently flushed it with ph’d water a week ago I’m using gh flora trio feeding 2 ml micro 1.25 ml grow and 2 ml of bloom I have had another plant with the same similar problems with a different nutrient it’s about 3 weeks into bloom the spots have been popping up for about a week now and the yellowing just started three days ago I’m growing in soil and I water about every two days what other info do you need thanks again

WHat's your PPM in your rez? Or nutes supply at those mL rateings? Try raising your lights or dimming them 20%??? What's your runoff Ph?

So I personally have only grown a handful of autoflower. But loads of photo periods plants. Autoflower really doesn't like any kind of change once their growing along well. Ya mentioned you flushed, bad mistake at week 3 of flower for any species. An over load of water/flushing will accomplish 2 things. 1. All your roots currently available nutes are flushed down the drain holes. 2. Its giving a mass dose of feed too quickly, hence the tops burning and lockout issues.
