Ok, So all I see is "Soil" in your diary. What nutrients are you using and how much, Next guess would be nutrient burn.
A lot of potting soil will be to strong for juvenile plants. Fox Farm Ocean Forest is a popular mix that does this.
Good call on the ocean forest. Just transplanted about a week and a half ago. Haven't used anything but calmag, clonex for seedlings, and recharge so far though.
She needs more nitrogen - calmag won't do anything. Give her some grow nutes and she should be fine. Good call on the Recharge, btw... that will definitely help with the uptake of nutes and improve your soil.
Good luck!
