They're in Rapid Rooters. I too thought they looked stretched but was more concerned about the leaf color. Right on, moving the light a little closer may not be a bad idea.

--They haven't been given any nutes. Is it better to add CalMag when nutrients begin or do it now?
colour Reviewed by colour on . Too soon for nutrient deficiencies? Drip T5 Distilled water @ 5.8 69-72 F 40-42 RH 18/6 cycle Watered 3x daily @ 10 min. increments. These 2 are in the 9th day of light. T5 sits 3-5 inches from top of plants. I've noticed they have slowed in growth and developed leaf discoloration. From what I've researched it looks like a P deficiency. Is it too soon to have nutrient deficiencies...? Rating: 5
