I am very new at growing cannabis and have recently run into problems with my seedling. It is about 19 days old and has started showing dark green spots and yellowing on the sides of the leaves. One part has even turned black an withered away. I am using fox farm soil. I water it every time the soil gets dry. I am using a T5 growing light and its placed about 2 ft away from it. I have a fan constantly blowing on it. I am use 12ml of B52 with every liter of water and have been using a ph test kit at 6.5unnamed.jpg

Definitely lay off the additives and give it clean water. Your pH sounds good. Just remember, less is more. FF is pretty rich, you shouldn't need any additional nutes until just before flowering.

A couple more things I'd like to add. It looks like you're only watering the base of the plant. You should soak the soil throughout your pot until its heavy, then let it nearly dry out before watering again. It also wouldn't hurt to lower your light to about 6 inches over the top to keep it from getting stretched and leggy.

Otherwise that's a pretty healthy seedling you've got there, just leave it be and let it do its thing :)
