What is your nute mix? Are you mixing to the full dose reccomended by the manufacturer? I dont use those nutes but in general its always a good idea to start at 50% mix or less and build up the concentration until the plants are happy. Also, are you using RO or plain tap water? Tip yellow can be many things including chlorine burn from tap water. Are you keeping temps, humidity and PH under control? Its hard to say what the problem is based on the limited info you provided.

nute mix is a 50% mix of reccomended doses
temps are 27 deg celcius res and 28 tent
ph is on average 5.8
ec 1.4
and using tap water but left out overnight for chlorine t evaporate
