So i have 17 auto blueberry plants in 2L soda bottles that sprouted on the 7th so exactly 7 days old today. On the 12/12/13 i lowered the lights from 3 feet away to just 2 foot away from the plants. The next morning the plants did not look very good and a couple of the leaves where pointing up not just at the tips but the whole leaves curling upwards.
Yesterday i raised the lights back to 3 foot away and after checking on the plants again today ive noticed nearly all of them are curling up and do not look healthy at all much worse than yesterday when i checked on them.
Also have some seedlings in 5oz cups and they are not showing any signs of this issue with the plants that are in the 2L soda bottles so i dont think its my soil mix? im using John Innes #1 seedling mix it does have time release nutes in it though.
Heres a picture of the seedlings in the 5oz cups that seem to be un effected.
Anyone have any idea as to whats causing this situation? i could just be overreacting as usual but with my limited grow experience (only one prior grow under my belt) thought i best ask the expert growers
