3rd week in Veg ?? PICS!!

Hello, this is my 1st veg on new hydro setup, Im using ebb&flow, watering about 11 times a day just cut down to 7, running 18/6 on lights, my nuts r... soul grow, soul grow amino aid and roots organic trinity. Im at about 1200-1300ppm and 6ph. Im using 2 t5s for light. Im getting some yellow to browning on the tips and sides of my leaves in v shape. The new growth seems to be fine. What can I do????

Kill it and start over lay off the water bro thats a little too much
