Leaf discolouration. Nutrient deficiency?
Leaves are discoloured and clawed. Started about a week ago with yellowing of tips and clawing at top of the plants. Now lots of leaves are slowly changing colour. Thought it was nitrogen toxicity but my runoff is 330ppm. Are they deficient in nutrients?

Calcium / PH issues? Did I take the correct steps?
Am I on the right track to remedy my plant's issues? Seems like calcium deficiency to me. Soil test comes in at just under 6.5, my reservoir water going in is 7.3ph, in case its actually a lack of calcium and not the PH i've top dressed gypsum (and epsom salts).

Yellow leaves at bottom. New growth good. How she looking?
Tried a new nutrient line, instant Pythian(sp?). Switched back now and she seems better. Should I be concerned at this point? New growth looks good to me. Although she seems droopy for this time of day. My theory is that the new line was more sensitive to warmer water temps.

Am I overwatering these seedlings? (Coco Coir) Please help, Thank you :)
These seedlings are about 3 weeks old in Coco coir. I PH the water to 5.8-6.2 everytime. I was watering every 1-2 days as the top soil dried out. Have I been overwatering? How much/often should I water them at this stage and should I wait for them to perk up before transplant?
