Flush your water. Try 100ppm.....200ml of calmag is going to kill your plants in 6 gallons of water.
Also, whats the temps in the area? Do you have a fan blowing acrossed your plant? How far away is the light?

That should of been 20ml not 200. Min/max at the canopy is 71.4/84.2*F. 79.0/73.2*F at the floor. 46-65% humidity. Light is about 9 inches away. No fan yet, Ill pick one up today. Still need a flush? I don't want to flush if it isn't needed, would feel like flushing money down the toilet.

whoa! 200ml had me worried there for a sec! .... OK, at only 9", the light is way too close,... T and RH are fine, but the proximity of the lights makes surface temps too high, and intensity too much,..back them up to at least 18",... As for the NFT and nute strength, I can't say much there, having never done any form of hydro yet,... but the light/heat stress will mess with nutrient transport, if the stomata close up and halt the flow of things from roots up,... watch those tips for yellowing, potential nute burn,.. don;t see much if any really now, what's there could be from the stress,...
