I'm back, thanks for all the help so far.

400w hps
Just finished Week 5 Flower
12/12
Fox Farms Nutes every other water (Tiger Bloom/Big Bloom. Using about 3/4 strength)
Watering about every 3 days (by weight)
Using PH Down to get my water to about 6.5-6.8
Let water sit for 48 hours before watering
Temps are now about 70 at dark, 78 while light.
Problem started with the largest fan leafs, now effecting whole plant (the two other plants seem to be just now starting in the early stages of the same problem)
Flushed a week ago, problem still seems to be spreading up the plant.
Used Epsom salt during the last water.
Examined for mites, can't find a damn thing.

Only have a few weeks to go and now I'm not sure if it's going to make it. Seems like it has to be something with the water/ph, but I can't seem to figure it out.

Hi purkles - are you growing in soil? I've had good luck dropping my PH down to about 6.0, then watering.

Those pictures however look like classic cal-mag deficiency. The rusts spots are a dead give away. Search for "the mj plant abuse guide", it will help you identify the issues. EPSOM Salts might help but, do it right, goto the store and buy some MagiCal or Cal-Mag plus. You can't reverse it but, you can stop it from further issues.

Thanks LJ.

I believe I've found my problem... My PH meter is way the fuck off. I figured my nutes, watering, and temps were all perfect, and I'm using brand new bags of Ocean Forest, so it had to be a PH issue. I decided I'd test the meter in some milk, figuring it should read right at 6.7.

NOPE. It read at 7.3-7.4

So all this time, I've been watering as low with a PH as low as 5.7--no wonder the plants aren't doing very well.

I did a flush last night on all three plants with water in the correct range, added some calmag, and hope that the two distressed plants pull through for two more weeks.
 
keep it real.

sounds about right, milk will get your through until you can get some cal solution milk should be around 6.5-6.7 so either way its not far enough off to hurt it can get you through. good luck man dont try and raise the ph fast it can stress the plant.
