3 weeks into flowering - help

I really really hope someone has some good news and/or good advice for me. I'm totally at odds to what's going on at this point. Fed them and then this started appearing?! Obviously I need to flush but my plant were all looking a little discolored for some reason but I don't know if it could be fungus or someshit from the soil being damp! i know i just don't want to do anything before i get some advice. I know for sure one is having terrible discoloration so I gave it calmag and it seems to have at least halted it cause the buds started growing but then the rest started becoming discolored so i gave them a light feeding and now they have these fucking blotches of shit around them. wtf -_-

Also, don't know if this makes a difference but my buds were smelling really strong and sweet and after this feed that this started happening the cheese smells like vomit/shit. normal?

*edit: all my plants are 3 weeks into flowering except the diesel which is near the end of flowering,.

Looks like a cal/mag problem but it would be good to know what your water is and how much cal/mag you have been giving, as well as any other feeding info you can share.

that's what id say too cal mag.

when I switched to flower i did away with the GH nutes and got some all purpose 20-20-20 feed, fed them lightly with it, only thing I did add now the second feed after two weeks of just water was some molasses. I also have this weird putrid smell now in the room, like vomit. I was reading molasses could do that. I think i'm just going to flush them and wait till they really dry out and re feed without the molasses.

edit: my water is distilled water ph to 6.4-6.7

Distilled water is best used with a cal/mag supplement every time. Keep that 20-20-20 pretty light.

I know it's timed release too so I wasn't planning on using for another two weeks. I gave it an 1/8 in a gallon. I guess i'm just in a funk, i just started flowering and they look like they're going to die before they get to fully flower.. First time grower so I'm panicking

1/8 in a gallon seems like alot.....buds still look good tho..it'll pull threw

damn 1/8 of a complete fert in a gallon is still a lot? then maybe i'm burning the shit out of them. I think i'll flush them out good with ph'd water and let them get dry to the bone before i feed them again at all.

Don't flush a plant with time release ferts, it doesn't work. Get some cal/mag in your water ASAP.

All right guys, I will try this and keep you guys updated.
