Green Gelato / Northern Light

You say "they are not in direct sunlight" - this is your problem!! They are not wilting, but stretching towards the light. This is purely caused by a lack of light, a lack of wind does not cause stretching. Transplant ASAP, those tiny cups will stunt your plants immensely and quite soon. You don't need to water constantly either, a good drink followed by a period to let them dry out a bit before re-watering is the go. Strangely, Jack Nicholson first tells you that they are getting too much light, then finishes by saying they need more light! Temps are fine and the seedlings NEED direct sunlight. My outdoor plants survive summers with temps up to 47 degrees Celsius and they are in full sun all day, every day, from birth to harvest and never suffer heat stress or other problems. I guess they have been growing that way for Millenia by now. Cannabis is a remarkably resilient and tough plant and not a delicate "Princess Perfect" plant that will fail if temps are one degree too high or pH is not exact! Hope this helps,...........
