My leaves are way worse than that. They are yellowing very rapidly and dying off. I don't think it's effecting my buds yet but I think after a while it will.
Is This normal?

Put up a couple good pics showing the top half of the worst plant and one showing the worst of the leaves.
Are the leaves all crispy and dry as they yellow or limp and saggy?

oh now I see what you're asking. I like that idea. I hadn't tried to target the water to like this much makes run off and then say a half cup less doesn't, but that sounds like a good idea to me imho. I've got plants about the size of yours and it looks like maybe you're in a 2 gal pot, and looks like good amount of perlite. And I would water I think it's a 12 oz cup. Depending on the plant but generally about that size I only have to water once every 2 to 4 days. That one I'd guess 3 days if it were a fabric pot, but more if plastic. I'd love to have plants that could use a watering every day but I just don't have it. Maybe if it were 1000 watts it would be a different story.

it's a 3 gal fabric pot. I have about 1/3 of perlite to 2/3 of soil. I have to water about every 3 to 4 days. Do you have any clue why my plants are doing what they re doing?

The first picture never happened to me so I defer to old med user. I think he said flush with the epsom because it could be a sulfur deficiency. I've seen something like the crusty leaves on the buds. I think that for me was a combo of spider mites and extremely overwatering the plant because I used to water every plant at the same time the same amount, therefore some got water when they didn't need it.

What do you use for water?
That looks like classic toxic salts buildup. Salts build up in the leaf tissue until it basically fries them from the inside.
I get that often even with RO water from low humidity making the plants drink a lot more water that they take up more nutrient salts with. Minerals in tap water make it even worse. They're all salts.
If you haven't flushed already you should. At least the same volume as the pot to reduce the salts in the pot. Soak it good to the point of runoff and let sit for at least a couple hours to make sure any salts are well dissolved then pour thru the amount of water the pot holds. Do it in the bathtub or basin so the water can drain freely. I couldn't move the last one I flushed so used a shop vac to suck up the water as the catch tray filled up. Goes faster if it can drain freely tho.
It won't fix what's wrong but will slow down the progression. Buds will still be good.
When you use the 3 gals for the flush you want to add it as fast as it will take it and run out.
Brita filters don't remove any of the minerals in your tap water. Do you have a ppm pen to check your water with? You can call your water supplier and get a copy of their water analysis report for free. They'll usually email you one. Should have ppm and list all the minerals in your water. Those minerals will build up in your soil with every watering like the scale does in a kettle or coffee maker.
I use RO water only for my plants and BUNN coffee maker to make sure everything runs smooth and if something goes wrong with the plants I don't have to worry that it might be the water I'm giving them.

You just want it saturated and can remove any runoff while it sits for a while.

I started weighing my plant every day to see if it needs water. to get a baseline I weighed when I transplanted before watering. Maybe a $25 postage scale is worth it at least for next time. You can use a little gram scale for babies, but a 3 gal pot probably weighs 10 lbs so you need a bigger scale. It's good for weighing sick cats, infants too. Even if your watering right it will be good to know for your peace of mind.

I lift my pots to get a feel for when they need water. Just have to hoist them a bit and not do a clean and jerk to feel the weight.
As the plant gets bigger and especially when it's getting loaded with buds it will weigh quite a bit more so that has to be taken into account.

I tried that but still kept second guessing myself. Is it light, in between? I had the scale already so now I'm used to it and I know to the tenth of an ounce which sweetheart needs waterI lift my pots to get a feel for when they need water.

My bigger ones I cant move cus there intermeshed in some wire for support, but I had a thought for how I might improve that for next time.

Won't hurt to add some epsom to the flush water I guess but the overall problem looks like to many salts and minerals from your tap water and ferts. What is the ppm of your tap water?
Back where we lived in BC we were on well water and it was high in manganese and smelled/tasted of rotten eggs. Tasted and smelled fine after going thru a Brita filter. When we moved here to northern Alberta we tried it on the town water and it did nothing to alter the muddy taste. We started buying RO water then and still do. Now that we live on an acreage we get our water from a dugout on the property and can't drink that either. pH of 8 and about 400ppm.
I use Epsom salts with my plants. Not all the time tho and not a lot. I'll toss in a heaping tsp to 5gal of water every three or four waterings. I use soilless ProMix HP to grow my plants in with AN 3-part hydro nutes and they have enough of most nutrients that I don't have to add anything and didn't for over 10 years growing in DWC other than a bit of Epsom. I started using a bit of CalMag a few years back but only about 1/4 of the recommended amount.
How many weeks have they been flowering now? Days even.

I have my plants like that sometimes too but squat in front with my elbows on my knees, grab the pot on each side and just rock back a bit to lift it an inch and feel the weight. Can do that sitting on something if squatting is hard on the knees or back. Getting that way with me for sure.

200 will still cause minerals to build up in the soil but only half as fast as 400 would. What those minerals consist of is another thing too. Some tap water is high in sodium, iron, manganese etc and that can cause problems like locking out other nutrients if there is too much of one thing. A water report is good to get so you can find out exactly what's there and what isn't.
Damn near ready to crop then so I wouldn't be too concerned about how they are now. Always the next run to make sure you do better. I've been at it 17 years here steady and still have my share of problems. Mostly from not staying on top of things like I should.
