I cant' figure out what the problem is, I've got 5 plants I just switched to flowering about 2 weeks ago, 3 are looking great and budding nicely, 1 has been dieing and not budding, and the other one is on that same path, spreading these Black marks all over the leaves, and then they turn yellow and curl up and are cruncy/die and i have to pull them off.. It spreads from the bottom leaves and gets all the way to the top leaves, only the newest growths are green, but the 2nd to newest growths are starting to get those black marks as well.. most of them have black on the tips of the leaves, but not all..

I water roughly the same amounts eveyrdya to the plants, but figuring this may be overwatering (and still think this might be the case) I've been drying out them a little bit, and only watering the dieing ones a little bit.. But after just giving it a little bit, the worse plant was very unahppy and started to droop again.. So I skipped watering completely yesterday and it got pretty dried out, and today I gave it a little water + epsom salt and it doesn't seem to be drooping like hell like it usually does around this time, but still its not looking happy... so maybe indeed its OverWatering.. the leaves are like rotting away?

Just wanted to see what you guys think, at first I thought it was calc def or mag def, and i hooked them up with calc but it did not help, and today i put a a tsp. of epsom salt for magensium in a gallon and fed gave them a little bit.. maybe 18 ounces.. because they were extremely dry

I've been reading all the deficiency issues and I couldn't come across this black/brown marks spreading on the leaves.. Even the stem vein becomes discolored and brown..

is this because of overwatering? how can I improve their health the fastest, just keep them dried out? just wondering if this may be something else and if I shoudl flush

thanks in advance for all your opinions and help!
