What's your water source, PPM, & PH before and after nutes?
What's your nute levels?

Looks like calcium lockout from nute OD to me...

I've tried a couple of different water sources, to no avail. I've used tap water, RO water, and distilled water, and still no change. My tap water measures 25ppm and 5.5 pH. I'm sure of this, since I had my tap water professionally tested a little while back. I've used a couple of different nute schedules, and I have also ruled out over fert. Now I'm running 2000ppm of CO2 at 90f day, 70f night. I've used 3 different brands of nutes, still no better. I've used GH 3-Part, Supernatural Aqua, and Advanced Nutrients Sensi 2 Part. I buffer my reservoir using Dolomite Lime, so it's probably not a Calcium def.

The buds come out fine, it's the leaves that look like shit.

I agree...I never had a calcium def. until I moved from city water to a country well...since adding Cal/mag the spots stopped....stay safe and best of luck

Doesn't dolomitic lime contain calcium?

Wow. i kinda forgot about this.. I ended up listining to texas kid and lowered my pbp to 15ml, raised calmag to 10ml, and lk at 10ml.. It cleard up for a while then went down him again.. I am now 1wk into flush, and ready to chop in the next 5-7days. I think my problem was not a nute issue honestly. I think it was an issue with the rockwool i was using, it is those little 1" cubes. My theory is the ph in them was fubard. Also i shifted them around and i had a bunch of fungus and knats living in them.. It is the first, and last time i use them..

HOWEVER.. here is some updated pics..LOL I think it turnd out ok for my first time.
