Is she ok?

Experimentgreen Thanks I did do a cal/mag does when I first noticed the lighter coloring just once. Will give her some more was worried only third grow first in winter and this plant had issues in the start.

I just started to give her as prescribed Kind bloom this week every 3 days then plain water. She was never given anything but water and for me letting her grow naturally I can't screw up. The soil is 2 parts black cow organic soil mixed with fox farms with added worm casing ,vermiculite and perlite. I have her and sister in homemade grow tent in shed outdoors where I use a heater to hold temps around 75 to 80 degree f and humidity around 35 to 55 percent. The seeds are from Seedsman as a freebie called sweet auto mix it says it could be a mandarin orange or some new purple types.
