Leaves are browning - hope my baby is not dying

[viosurge]

This is an indoor hydro grow vegging under a GrowLight CFL 6400k 125 Watt light currently sitting 18 inches from the top of the plant. Humidity in the room averages around 40% and the temp fluctuates between 75 and 80 degrees. The plant is a Banana Kush clone I picked up from a local dispensary - around 2 weeks old. The lights are on 24 as of right now. It's fed Pure Blend Pro by Botanucare 3-1.5-4. I mixed about 4ml of Pure Blend Pro per gallon of water the first week. I just dumped and remixed about 7ml per gallon for week 2. Each gallon of water gets 1ml of SUPERthrive. Right now the pH is 6.0. The first week I did have some pH balance issues. I had to add pH up and pH down to even it out. I did settle it out but I'm wondering if maybe it was too much for the plant.

For some reason the plant is looking sickly and it has since its third day home. The tips of the leaves are turning brown and curling up - even with brand new growth. The edge of older leaves are browning as well - really appears as burn. I cannot define the issue though - be it nutrient burn, heat, too much salt..etc.

Hope the pictures help define the issue. This is my first grow. Thanks for taking the time to help a brother out.
