new strain that had an early PH issue

I had a low PH problem for 2 days early into 12 and 12 the leaves curled under. I fixed the PH and it has now been a total of 77 days 12 and 12, and the look like they are in week 2. The buds look as though they may be getting a little bigger but it is so slight I am not sure. The 2 plants are large Black Widow, first time running this one. The roots are beautiful and white drinking fine. My question is simple will they eventually finish or is it possible for them to not finish flowering. I actually have a few red hairs.
Thanks

Have u ran ur set up successfully before? They look horrible for being 77 days into flower either u stressed them to the max when u started and the buds never developed which i think could be the factor or the strain just sucks!!

Yes, I have run this set up many times without a problem as you can see from my avatar. They were stressed by PH problem. The strain is Black Widow which does not suck but I have never ran it before. Maybe I just need to get better with sativa dom plants. My question is has anyone ever seen a plant not finish flowering once started, will they fatten up or should I just pull these.

Water and advanced nutes B-52 only till they get going again. No growth in 5-7 days chop them you're wasting time.

Thank you for your replies, They seem to be drinking well, it is just hard to see growth on the buds, the plants are large 6 feet 6 inches with the top 2 and a half feet bent over which would make them 9 feet. It does seem like there is slight growth in the bud area. My experience has been with indica dom mostly, so, I was not sure if they would finish. Hate to cut them but I understand that it is better to cut loses but it is hard sometimes to know where the line is. I am going to move them to another smaller room under an LED only may not be enough light but at lest I don't have to hold up my flower room. I have Nuken ready to go into the room, which I know well. But I need to get better with sats. The LED I am going to use is Stealth Grow SG602 LED products: SG 1250 HO | SG 1202 | SG602 | SG602 VEG - Stealth Grow, LLC does anyone have any input on this idea.
