Can't figure it out... HELP???

I cant figure out what is wrong. It looks like mag. def. so i gave here some calmag but it didn't help. Now its moving up the plant and doin this to the upper leaves, It's driving me crazy. +rep to anyone that can tell me what it is. My ph runoff was a bit acidic the other day don't know if that might be a factor, I'm a noob in desperate need of advice.

Cmon somebody has to know??? any input would be appreciated

ph can have a lot to do with it. To high or low can cause root lock and you will not get the micro and macro nutes she needs.

Can you test ppm of desolved solids in your grow?

i don't have a ppm meter but can get one tomorrow

I'm just wondering if it's root lock or nute burn?

I dont think its nute burn because i havent fed her much, a few doses at 1/4 and a few doses of half strength over a period of 2 weeks and i only gave her F.F. big bloom and a tablespoon on calmag to a gallon of water twice.

Can you get the ph around 6.5- 6.8

I think so.. my water is almost at a ph of 8 so Ive been lowering it with vinegar to about 6.5 is that ok? do you know why my runoff is so low though it was at like a 6 maybe a bit lower before i flushed it

Perfect. Sounds like you had a bit of a lock up, plants in soil take a little longer to show recovery.

Bumppppppp

anyone????

looks like nute burn. flushed latley??
