without knowing more info on your grow this is what I would recommend.Pull the few leaves that are discolored,if I had to guess you have some sort of pest problem.Check your plants from top to bottom,underleaves especially,usually if just one or two leaves are starting to erode then the problem is not an infestation YET.If you can get your hands on some neem oil then use it daily...the plants really appreciate it and its an organic pesticide that can be used up until the day of harvest.It simply inhibits the insects ability to reproduce and also strips the membranes of the insects skin...it is relatively inexpensive and easy to use just follow the reccomendations on the bottle....remember tho...DONT USE ANTIBACTERIAL soap when mixing.It kills the goodies in the neem and makes it useless......any more questions or if this does not solve your problem let me know and I would be glad to help further..............Phil...

I also noticed that your plants are on an unusual light cycle regardless if you are vegging or budding........it is usually a good idea to have your vegging plants on a 18(on) and 6(off) schedule.......unless your lifestyle and or your grow room requires your 14 and 10 cycle then I would reconsider your lighting schedule.....of course you already know that flowering in most plants need a 12 and 12 schedule.............any questions just let me know....Phil

You need to fill out the troubleshooting form first off. Second, do not take any advice until you fill out the troubleshooting form. Third, fill out the troubleshooting form.
You have given virtually zero information for anyone to be able to begin guessing at what may be wrong.
Fourth, do not spray your plants every day w/ neem.

DWC? What are your water temps? Go fill out the form. Otherwise you are not going to get much help, and any advice you get will most likely not be very helpful, and if you follow it, may in fact compound and create brand new problems for you. It may be that you have more than 1 problem.
My 2 cents.

Looks like nute burn. There are plant trouble charts that you can compare your plants to theri pictures. Put them babies on 24/7 light until you want to bud them
