@peachfuzz this is the recipe I’m going off of. Except I’m only using 3ml of Calmag per gallon. Not sure what ppm was before the Hydroguard was added though.
@WickedAle
Isn’t CalMag a must if I’m using RO water?
If your water starts out at a ppm of 15 or lower because your using ro water , then I always use cal-mag in the mix and when there’s not enough magnesium , then I’ll throw in a little Epsom salt… 
I’m not sure I would be running such a high ppm for such a young plant … if it were me , I wouldn’t be over 150 ppm , that’s just me tho…
I usually expect my plants to act a little funny when they’re just starting out and not established…

What water temp is to cold for hydro? My water temp was 74 degrees so I threw a frozen water bottle in the bucket and in like 30-45 min it’s down to 66
I don’t do hydro but I think in low 60s is ideal
Between 66 and 70 is your target temps to keep them happy and healthy…
Dr I only have1 hydro grow under my belt these folks will put you on the right path I had no problems with my first chalked it up to dumb luck I had more problems with my last soil grow good luck will be watching
