I think most who see this are going to ask 'what the problem may be'....nothing stands out to me. Carry on and good luck.

Overwatering and too much nitrogen.

Those bud leaves curling like that is pretty normal for a lot of strains. Some Afghani Kush I grew a few years back had lots of those but I've had them on other non-kush strains too.
Pretty sure it's damn near impossible to overwater when doing DWC.

Ive had the same issue, i imagine one of your nute bottles are the main nitrogen and cal mag source.....? With mine i did a bucket changeout and added a bit more of part B (higher in PK) and reduce my part A (higher in N) to about 1/4 what i had been using. So basically reduced nitrogen in my solution and let the plant feed off the excess nitrogen in the leaves for about a week if i remember right. Sugar leaves lightened and perked up. Buds started exploding with growth after this. This particular pheno was very nitrogen sensitive in flower. Hope this helps!!

Too much nitrogen in flower can drastically slow down bud production. Can become a big problem from such an easy fix!! How do you flush in DWC??

I grow in soil so I don’t know but essentially just feeding plain water would be a flush for dwc right?? Maybe short period too as it’s their only access to nutes, unlike soil. I still wouldn’t flush though just cut back on the nitrogen.

No, with hydro you provide everything for your plants uptake. Dumping all the solution out and replacing it with fresh nutes often throughout a grow is very important for a consistant healthy crop. I wont go into all the details here. But it will be the best way for scaryt to know whats actually in that solution if he wants to correct his nitrogen toxicity. If in soil feeding plain water would be a flush. Hydros different man.

Yeah It’s vastly different, my post basically gave a general idea of how I thought it would be done.

More of less what I would do in soil for a flush honestly. I do realize it’s totally different though.

Sounds like a good plan to me. I can see a tiny bit of tip burn on your leaves but nothing to stress about nute strength wise in my opinion. Just a higher ratio of nitrogen than what this particular plant needs id just recommend to keep a close eye on them over the next week or so and when leaves lighten a little and sugar leaves perk up and come to life, you may want to up your nitrogen to maybe half strength? Thats what i did anyway and it worked a treat.

And looks good man! Im sure your going to be happy come harvest time!!

And just double check that part A is the nitrogen rich one of the two. I use different nutes, so my part A could be your part B? If you get what i mean?

I did some grows in DWC and soilless using Sensi Grow for veg and Connoisseur for flower both being two part nutes and found there to be too much N in flower, specifically late flower. I got the 3-part nutes almost three years ago, (used the 3-part for a decade before the 2-part), and after the stretch feed Lucas Formula style to reduce the N. It still gives them enough N for their needs but not so much it inhibits bud production. They still need lots of N during the stretch as they are building lots of new growth and it's essential for that.
More flexibility with the 3-part I find and I do add a bit of Epsom Salts to make sure they get enough Mg and some extra sulfur for the resin.
For those not familiar with the Lucas Formula method it basically drop the Grow and use half as much Micro as Bloom. If you look it up it will say X# of mls/L of each but I go by how much I want to raise my ppm without changing nutes. If they're lucky they get one change after the stretch for the whole grow.
With AN 3-part and likely GH too: I checked as I added 1ml/L of each to 2 different DWC tubs holding 50L each.
1ml/L Grow = 90ppm
" Micro = 140ppm
" Bloom = 110ppm
So by starting a new tub with clones and after adding the appropriate amount of CalMag I end up with just a bit over 300ppm which is just right for starting rooted clones in DWC. Then I just add more nutes to raise the ppm as the plants get bigger and can handle more.
