What is your medium and water source?
Tap water and using general hydroponics nutrients.

I meant what medium are you growing in?
Hydro
How is your EC pH? At what levels and how they are moving
The left side seems to be more effected? Is it under different light?
They seem to be getting bit too much light, atleast under the conditions they are in.
Any idea how much light are you giving?
Looks a bit dry too.
Humidities and airflow up to par?
On the nutrient side as you are still vegging and depending how often you have changed your water
the nutrient ratios maybe have gone off too much.
Lucas formula 2:1 bloom/micro ratios comes up close to NPK 1:1:2 with :1 calcium.
So it has bit too much K related to N and Ca for vegging. (calcium nitrate would be good addon to get more N+Ca for vegging with lucas formula.)
And if the K accumulates it interferes with Mg and Ca uptake.

That didn't answer the question? Hydro is a way of growing, not a medium? If I ask what hydroponic system you're running and how does the roots sit in the water/nutrient solution?
Do they hang free in a neoprene collar without any medium like hydroton/clay pellets, grow stones or other medium in a net pot?
We need proper data to be able to help like what everyone is trying to ask you what nutrients you use and at what strength and how you actually operate the system? I'm afraid without proper data you only get half ass guesses.
All the best of luck!
Cheers!
Hydroton pellets
Like I said I’m new to hydro so I’m trying to go straight Lucas formula didn’t plan to run into any issues. Was going to flower soon but with what she’s doing I want to wait till she’s fixed.

You need to answer questions and tell us how you operate the system and post more relevant information.
I'm doing a last attempt at helping you out. How does the roots look and do you do any preventative work to protect them against pathogens like Pythium root rot?
Many people use oxidizers to clean the roots from biofilm, other people use bacteria cultures in combination with a water chiller.
How do you keep the reservoir? Do you do weekly reservoir changes? It's very important running smaller reservoirs to keep it clean and keeping nasties away and reset the mineral ratios to stop inbalances and lockouts.
Cheers!

If it were me id drop your ppm to 600 and keep your pH between 5.8 - 6.2
It might sound counter productive but they drink better and the nutrient uptake is better , and id add a dash of bleech to your resevoir to prevent future issues if they havent already started . And what sort of hydro system are you running ?
A flood and drain
Deep Water Culture
Recirculated Deep Water Culture
