i am useing botanicare and karma and my leaf tips are curling under

The claw can be a sign of overwatering. Make sure to let the roots dry before applying anything again. This is a common issue no matter what products you use. If it is a slight root rot from excess watering Botanicare's AquaSheild can work miracles and bring back healthy white root tissues. Just don't apply it until the soil is on the dry side. Also, you can foliar both those products to get what is needed to the top of your plant without depending on root uptake. Only foliar with the lamps OFF.
 
drain half and add pure water, also, flush your plants inbetween floods with plain water for a bit. sounds like a hot mix, check ph of course, and temps. good luck, snap pics?

Your plants look pretty healthy to me. Definitely not overfed. I ran their whole line for years in ebb and flow hydro with hydroton rocks. I settled on using about 75% of their recommended (not aggressive) feeding dosage. How often are you bottom watering them? Once the rootballs fill those containers they will need a much higher frequency of irrigation.
 
bout every 2 days right now i only water when they get light. and ya botanacare is a little stong that sounds about right at 75%..i was going to trim at 2 weeks bud once the 2 week strech stop's and all the top fill in the i will pick and choose whitch one and all the popcorn
