Hydroponic Plant Problems

I started this grow in December. I cracked a few seeds and a few died along the way. I've got one plant left. It's a clone of one of the originals and it's been through a lot. All my plants that died started to look like this. The plant in the photos just got this big. It had been tiny for 2 months. I emptied some off the pebbles today and the roots look good. Please someone help.
Conditions:
Temp= 78F
Ebb and Flow in clay pebbles
EC=1.5
pH= (5.8-6.4)
Nutes=I've tried different ones. All had the same problems.
Pathogen control= Pool shock or H2O2

What strain is that? The fan leaves look messed up; they're just growing one finger each.

Those are some sick babies. They aren't supposed to look like that. Those are 6 months old? I have some in ebb and flow that are 2 weeks old that are almost that big. I just run Floranova at 1 EC. That pathogen control doesn't sound too healthy to me.

I think it’s GSC. I’ve read that they’ll grow single blade fan leaves when they’re stressed.

Anyone know what deficiency it looks like? Disregard the size and weird fan leaves. If I can fix the environment the leaves should return to normal.

Looks like you might have your light hours messed up.

That plant is doomed, it looked like it completely revegged and it's not going to get any better unless you put another 6 months into it, by revegging and flowering again...sorry to be the bearer of bad news.

Start again, Fix your errors and things might improve.

Good read. Especially for those who recycle.

Looks like too many floods with high nutrients. You shouldn't need that pathogen control for daily use. What is your watering schedule? Those plants look they have sitting in water. Probably need to reduce your flooding frequency.

Looks to me like the light cycle hasn't been consistent and they are stuck in a twilight zone of flower vs veg. I'd make sure they are on a timer for at least 18 hours of light or even 24 hrs to get them vegging strong again. Or go 12/12 and flower them out now to make way for new plants grown right.

Single blades are not a strain related thing but evidence of a plant transitioning from flower back to veg and are often mis-shaped or otherwise 'different' until full veg is achieved.

The frequency is 1 flood/ 2 hours. I've got an ORP meter that I use to keep the potential at ~500 mV. That usually means 0.15g of 65% Calcium Hypochlorite pool shock every 2-3 days.

Believe it or not these plants have been under 24 hour light forever. I don't even have a timer connected to the light. It's very strange. When the original plant was a seedling it had fan leaves with 3 fingers.

I still don't know the problem. I've used Canna Aqua nutes. I'm using Dynagro Foliage Pro now @ EC=1.5. My tap water is very soft. My Blue Lab Truncheon shows no reading from the tap. I've added CalMag recently and that has seemed to help. Still lost

You just said what the problem was, and it was the same thing me and meds told you...that plant needs 12 hours light and 12 hours complete darkness and I'm talking pitch black, without interruption!, For it to flower normally...

I don’t want it to flower. This is supposed to be a mother.

Start over. You're wasting time with that plant.

Well then it's not getting enough light, lol...

And if your going to say "it is" , well... obviously not, because if it was receiving enough light for 18 hours...let alone 24, it would be in full veg state.

That thing is a mess ,confused in a state of veg and flower . Start again...use enough light and veg nutes with plenty of nitrogen.
