Help 3 weeks 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????

First off ..... your PPM is WAAAYYYYYYYY too high for those small plants. Those plants have just started their veg stage and should probably not be getting more then 600 PPM.

You need to flush those plants with some PH water only to get the salts out of them. Also... get your PH down to between 5.7 - 5.8.
