Need help plant problems please read

i am an experienced grower who recently bought a new house so i had to tear down the old room i grew in for the past 6 years or so and build a new room in my new place. in the old room i had everything dialed in a have been producing seriously quality bud and good amount for the number of plants. i was steadily pulling over 2 pounds from 4 to 6 plants. now i have to start all over again. things with the new house took alot longer then i expected so i didnt get to start building my new room alot later then i wanted so i decided to start them in a closet and move them into the room when it was finished. Now i will admit that i didnt exactly put the required attention that i should have to the plants and now i am stuck with the question of is it worth it to try and fix them or cut my losses and start over. I dropped 3-Purple Cheese Auto and only two made it and also one- Pineapple express over a month ago- Oct.18. I do DWC and have always started my plants off in an aerogarden then moved them to the bigger buckets. This time they were left in the aerogarden longer then i normally would leave it and also i wasnt super diligent with keeping up with ph and ppm levels until the past few weeks. I put them under an 8 tube 4ft T5 strip for the past three weeks while still in the aerogarden base. Throuhgout this time they never looked great but not that bad and were growing. I moved the plants into the big main room about two weeks ago and into their own buckets with a controller and resovoir. I just passed the start of week three of flower and am not liking what i am seeing. all the leaves are curling up and it def shows signs of what seems to be calcium deficiency. I have already figured out that i have much harder water in my new place so i am wondering a few things;
1-what is the curling leaves about?
2- have i let them go to long and should i cut my losses and start over with new seeds?
3- can i fix things to where it produces anything at all in these last 5 weeks under a 1000 HPS?

I guess a picture of the situation would be out of the question.

lights turned off before i could snap one i will add it tomorrow

I know the HPS light makes the picture messed up but I can't turn that off nor take plants out of the buckets so hopefully someone knows what is happening with these

Well it looks like a nute burn but I know nothing about hydro or your setup so can't really comment.

I think if you get your problem figured out soon they would be worth saving and see what you get.

Looks like a micro nute issue to me. Do you have micro nutrients being supplied to them as it looks like a nutrient lockout. I would just dump the entire buckets(keep the plants), clena out the buckets and refill them.

That looks like either calmag deficiency or nutrient burn. Check the EC if your mix. Do a flush with just pH water and start over with 1/2 strength nuts and see if it helps or gets worse after 2-3 days.

we can safely say you won't be pulling two pound of those unless u turn them back to veg an get them healthy looking an growing fast again, don't understand why u would put such bad looking plants into flower with 6 years experience.

I have moved an had troubles myself on the first few grows an blamed the water u need keep eye on the PH an PPM as u have already said yourself, are they even eating the nutrients up just going off the pics i would say they are not.

Haha I know I don't think I will get two ounces at this rate. They are auto flower seeds I was trying for the first time 60 days from when the pop is what the website said . I am not proud of this at all trust me but need something to hold me over till I get things rolling right again. Here's a pic of what I am used to.
