Probably mag. Mix 1/8 teaspoon Epsom salt in a quart and spray them good once every couple days till they green up. You using calmag?
 
Light green cannabis leaves are usually caused by a nutrient deficiency, an imbalance in the pH level of the soil, or too much water.
but follow gemtrees advice first, if it don't work, you can cross it off the list.
 
Got her straightening out but looks like a new problem has came up.

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.

Hydro

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!
 
Using cal mag plus by botanic are also. Just what it recommended for 5 gallons. I’m new to hydro so all bare with me, this is my first grow with it. She is 3 months along vegging. Humidity and lights I believe are fine. I’ve been running my ppm in the 1200 range.

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!
 
Roots look fine. I am not running anything extra for the roots.. She’s had two flushes, once per month, No chiller. I’m trying to give you answers , apologies.
 
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
Etc
