Hey Tiny, I think they are about 3 weeks old(give a few days, I dont think they are younger then that at all). They kind of had their life cycle delayed a little due to me changing the rez containers and what not, but for the last week, a pure 7 days, they have been loving life and growing well! They are pure green and the roots are just now starting to poke through and enter the water so today im lowering the water level so there is more of an air gap. I think they have been in this rez for 7 days or so. The plants have still been uptaking nutes I think because I had my bubbles bouncing into the bottom of the baskets. :thumbsup: On a side note, the plants leaves are curling up, in a form of a taco, and I have my suspicions why.... I read some interesting info on a lot of peoples threads but all I could find for this is soil. Its coming down to heat stress, as the plant is sweating.. Caused by lights being to close or too much wind velocity for extended periods of time. Well the lights were a little close because I hadnt moved them in a week, and the babies got a little bit taller... So we will see if thats all I needed. In the room im using, I do have an intake for fresh air. Also, I do have a fan that blows over the canopy. This isnt even close to keeping the air temps down, so I keep the main door halfway open and use a fan to blow in the air from the rest of the house. I can usually keep the room at a solid 82, but there are a few times I saw 90 Weird and wacky Washington weather... The only other thing I read that could be a cause is a nute deficiency in Fe or Mg .. I kinda doubt that since I gave them a good dose of nutes when I mixed the rez.
