If youre doing DWC - They look overfed, i.e Youre solution is too high and drowning the roots... If this is a DWC, you need to make sure only the bottom of the roots are hanging in the solution. and top feed until the roots get long enough to allow this.

looks like PH to me, nute burn would show on the tips of the leafs first.

pH
Improper pH can cause an abundance of problems that you might easily confuse with other problems or deficiencies.
A pH imbalance may also be the cause of the deficiencies in the first place. pH in soil is best in the range of 6 up to 7.5, and in a Hydroponic system it?s best at 5.2-5.8.

Only about 20% max of the roots should be in the solution, the rest will be hanging in the air. Lots of first time DWC'ers completely submerge all the roots..... I'm sure youre not making this error though, are you?? lol

yea I did make that error. so its not too much nutes its just drowning?

Yes, to me it looks like thats your problem. The roots like air even more than they like your nutes. A fully grown plant will probably only have the bottom inch or 2 of the roots in the solution. ... Obviously the roots need to be long enough to 'hang' in the first place.
If the roots are not long enough at the moment to 'hang', this is what 'I' would do...... Dont worry about the nute bath at the moment. Manually feed them from above until the roots grow and are able to hang through the net pots. .... Then make up your solution, and keep just the bottom of those roots in the solution. Osmosis will do the rest.

yea they hang through the net pot. So I should just let the water go up to the bottom of the net pot?

No, wait until those roots hang a couple of inches below the bottom of your pot. Then you will be ready to do the bubbling solution thing. ..... They DO look like theyve been drowning in your nute solution and this has caused the burning you see.
Feed from above a slightly weaker solution and in a few days those roots will be 4 or 5 inches long. THEN just let the bottom inch hang in your solution

Hydrogen peroxide is used to keep the solution from getting slimey..... Off the top of my head I dont remember how much of the stuff you need to put in..... You dont need it until youre doing the bubbling thing, but when I ran a DWC (Deep Water Culture) setup I defo used it. Its needed.
It goes without saying the roots and solution should be kept in pitch dark. ....Light will cause the solution to slime up over time. H2O2 will help prevent this.
