Please take a photo of plant with natural light. From the tips looks like nute burn. Another DWC person will answer soon. I am soil person.

I would say you are under feeding but dont know what conversion your ppm meter uses. Also what is the water ppm/EC before adding nutes? How are the roots looking? What is the temp of the res?

Water ppm before adding nutes was about 22-25(using r.o water)
Reservoir temperature is 22°C at lights off and 24°C at lights on
Iam not sure about the ppm pen iam using ive ordered a better ppm pen
iam using flora micro(2.5ml/gallon) flora grow(2.5 ml/ gallon) flora bloom (2.5ml/gallon) cal mag(4 ml/gallon)
