Deficiency prob I'm pretty sure

wus up guys I need some help. I'm not sure exactly what my problem is. I think I have a magnesium prob. It starts by just slight changing from green to more and more yellow it start towards the end of the leaves but not at the tips. Once it starts yellowing it gets worse and worse till it turns brown. Any help is greatly appreciated. Take a look at the 2 pics I took

im guess for now unitl you give us some info about your nutes

but I think your over feeding and locking out magnesium

whats the medium
what fertilizers and hom much

hmmm... that looks like straight up scorched leaves from overfertilization. see the tips. see the plant overall color. then see the frying. that's what i think.. fresh ph'd water for a while...

Yea I don't think that's the problem cuz I don't feed bites but every 3rd water and at that I dilute it over half cuz this damn cheese has been so sensitive it's been 2 plain ph'Ed water cycles over 5 days outdoors. It seems that jts spreading.

MOST of Thebes's the burn is kinda old I'm talking bout the discoloration that's starting in the middle of the leaves then spreading and slowly turning brown

just because you feed infrequently doesn't mean the EC of your solution isn't too hot

if your mixing the ferts too strong the plant will respond negatively to the high salinity and then you water plain water only for several days to leach out the excess...

youd be better off feeding a lower strength solution more frequently

of course that's assuming you are indeed mixing it too strong

I know that I'm not an idiot. Trust me I know I'm not mixing to strong and also it's been 13 days since I've used any nutes

Well, then why don't you feed her already.

If you're sure you know it's not overfed like you say,
Could try mixing a nutrient solution at half strength, a complete balanced nutrient solution and flush through 3 times pot volume and then leave it to dry see wusup, if balance is off, will at least give balanced full nutrient compliment again. and maybe wont see improvement even after a clean watering or 2 after that 'treatment'. and if that doesn't show improvement then next guess would be some pH out of whack?
