Tomato Plant - Leaf Health Issues

DanenP · June 22, 2015

Hello everyone!!

This is my first time posting. I've grown 4 varieties of tomato plants from seed. I'm using a High Pressure Aeroponic system. Everything had been going well until recently. Below is a quick rundown of the grow room specs along with the issues I'm seeing. At this point I'm a bit stumped. I'm not sure what is off.

Any help would be greatly appreciated!
Grown from seed
6 weeks old
Grown using High Pressure Aeroponics (roots sprayed with very fine nutrient mist)
Reservoir
ppm: 800
pH: 6.0
Temp: 70F
Environment
Day Temp: 75-78F
Night Temp: 68-70F
Humidity: 60%
Lights on: 16hr/day
Lights: 4ft, 2 bulb T5 VHO

Could this be a Calcium - Magnesium deficiency or nutrient burn?

the rolled up dead edges looks like tip burn to me, but I think 800ppm is a long way from causing that.
Have you been changing your nutrient solution? Dont know about the others.

I have kept it fairly consistent. I'm using General Hydroponics and following their nutrient feed schedule as well. I'm using High Pressure Aeroponics which sprays a very fine "fog-like" mist on the roots. I've read that you might have to reduce the nutrient concentration to avoid burn with these systems. However, I'm not sure if that's true and if nute burn is actually what I'm dealing with.
