Am i missing any key nutes or do i need to flush m...

Hi buddy! I would make a perfect nutrient solution with perfect pH and either flush with 3 times the amount as you normally would or if you can put the whole pot in a nutrient solution bath. So the soil can suck up the perfect EC and pH. Your plant is a bit small for the pot and I suppose that ctreated problems, you might have no nutrients where the roots are and many where no roots are. That's my guess. Happy growing!

Nitrogen deficiency from (probably) switching to bloom nutrients too early. A couple of half strength feeds with grow nutrients will prevent it from getting too much worse, but it won't cure what is already damaged. You still have 4-6 weeks to go, so don't be afraid of giving a couple of feeds with grow nutrients before going back to bloom ferts.

This is nitrogen deficiency and probably phosphorus deficiency. Just a proper feeding with NPK for flowering will help.
