Large brown spots and yellowing all over

Hello,

I have a Euphoria plant 3 weeks into flowering and the yellowing and brown spots have become increasingly worse.




-Indoors
- Fox Farm at about 1/4 strength - water is at about 6.0 - 6.5 after adding nutes but I don't check every single time.
- Using Sunshine #4 peatmoss with some chicken poo, worm castings and lime added. also its about 35% perlite if that matters.
- 3 weeks into flowering.


I have read up on this a bit and think I have been over feeding the plant. but it also looks like a cal/mag deff, I was thinking I might just flush it with ph adjusted water but, Honestly i really can't tell and i don't want to make matters worse so if anyone can help that would be greatly appreciated!!!!

I second that, probably not overfeeding in fact it looks yellow probably nitrogen, or iron defiency aswell.

Nute burn usually burns the tips upwards, as it progresses it burns most of the plant the same way.

pic 1 is calcium deficiency... your plant doesnt have this. dont add the cal/mag yet because it competes with N for binding spots on the roots(the molecules are of similar size).

that plant is N deficient; the lower leaves are yellowing/dieing, and its traveling up the plant. also the new growth tips usually have this slight bright green(almost yellow) color in the center when they are eating enough nutes, and i dont see that...

so feed with half strength(900-1500ppm) every other watering... it will recover after a feeding.
