[Up in smoke]

Hi I am so lost I don't know where to begin everything started so good then it all went down hill. So here is my set up I'm growing in 3x3x72 tent with a 600 watt digital ballast im using roots organic for soil and rock nutrients I have 1 white widow xx, 2 auto night queens ,2 vast and fast ,1 sucker punch and 1 narcotic kush all in 5 gallon bucket except one is in a 4 gallon. 2 4 inch clip fans and 4 inch inline fan and carbon filter when I started feeding nuits I started at half strength I recently took it up to full strength now I first noticed my narcotic kush getting like rust spots on the leaves and the buds stop growing and it went from a couple of leaves to the whole plant now 2 of my other plants are looking like there about to do the same thing so I went and got some cal mag and and gave it cal mag yesterday but today they looked liked the got worse they were drooping looking I can't post pics till the light comes back on in a couple hours but I need any help I can get plz

Hi up in smoke, you're gonna need to get some pics up, you're plants are in flower so I'm guessing a cal mag def would have shown up before now, I'm growing some 2fast2vast myself at the moment and every time I feed them they droop and they're in coco, don't water em any more and get some pics up as quick as you can, good luck.

hey bud! Are you using the Upload a File button? doesn't look like it,...that may be why? ...these are all coming in as attachments for some reason,...
....anyway, it's hard to tell in the pics, due to the HPS light messing with color rendering, which kames diagnostics more difficult,.. if you can, try getting pics in normal lighting, and some closer shot of affected leaves,.. That said, I think it Ca defc., but other's may be in play,... it takes a couple-few days for the Ca to get in there and working, unless you foliar spray, which during bloom, isn't the best option unless things are really bad,... i think I see some tip yellowing, likely a bit of nute burn, so dial back to half str. for now,... which Ca-mg product do you have?

Hey thanks for responding and yes I am using the upload a file button and I'm using calimag

sounds like you over indulge on the nutes, that can give you a nutrient lock up..best solution I can give is to flush them with purified or spring water , you can use advanced nutrients FINAL PHASE, or you can drench them for 2 or 3 days, one drench for each day.. each time you drench them you must let them drain out a lot, after the few days of drenching is over wait another 3 or 4 days and restart your nutes. don't go full strength wait about a week then up it a little , if you see the leaf tips turning brown , you over indulged on the nutes..I know this sounds like a plug for advanced nutrients,,but they are prob the best nutes to grow weed with... in my opinion

Waira's always got great advice! If you can take a couple pics of a couple bad leaves with the camera flash on, it'll help making more accurate colors of the issue.

So are they in coco or soil? It does kinda look like it might be nute burn and/or a Ca deficiency. See if you can take a couple flash pics so we can get an accurate color.
