Plants are short and stalky. Ive only fed them distilled water, no fertilizer and ive only watered them one time right when I transplanted. One of the Strawberry Cough has a bit of yellowing on the tips of the bigger leaves. The Blackberry Kush and Strawberry cough have some leaf curling. This may be due to too much light. My light is over 5 feet above the plants and on the lowest setting.
