New Grower First Grow - HiJack & Trans Siberian Autos under LED

Should I switch to tap water or stick w distilled (obviously supplementing the distilled w calmag)?

Personally i'd go for the tap water but leave it out (bottle lid open) for 24 hours for the chlorine to evaporate.

How far should my 270w full spec led be from my 1.5 wk old plants? Currently hanging @ 30 inches
That sounds about right.

I would personally let the plant grow to within 10 inches of the light from here and then raise the light as the plant grows keeping a 10 inch distance as long as you can.

For more comprehensive LED light height advice, i'd follow tangs guides!

I rcvd my calmag today. Mixed 1 tsp in a gallon of my distilled water and fed about 1/3 gallon. I also gave about 1.5 sprays over the leaves. Hopefully this helps and doesn't make things worse. Is there anything I need to be on the look out for after giving calmag? Thanks again for your help oldster!
 
image.jpgimage.jpgCal/mag seemed to have helped a bit as her growth has been excellent in 14 days. Stinky already too! Had to flush my hijack auto due to the ppms being to high (1200-1300) for a 5 day old seedling is a bit rough. She's down to 600ish now and recovering. Thanks for all the advice!
 
If you've got the space to let her grow up then try raising the light about 6" ... looks great ...
 
Will do Chester, thanks. Not sure if you noticed in the pics, but I ended up taking some landscaping sheers and cut about 4" off the lip of the pot.
