Sometimes seeds are just a little lame. Prop them up, put a mild breeze on up. Get a legit way of PHing or go to soil.

could it be the cold also? cuz it was 70 degrees in the grow room.i have a digital temp gauge.i also had a fan blowing inside the box...would to much nutes do this.wish i could get some help.i been all over this site looking for answer sagging plants.the roots are all white and ice and the plants are green what could it be are they weak?

Last time I saw this happen I propped the plant up and it was fine. I think that the little ones sometimes over grow themselves out a bit and end up being to successful for their own good. This could be due to a nutrient or hormone syndrome. I have never had the problem take more then a few days to get over but at the same time I am not all that exp with hydro.

Like I said get the right equip to do the hydro job or don't do it at all. Soil is pretty awesome and is the perfect place to learn.

Also those bulbs should be like... two inches away from the plants.

prop them up, give them some wind, a fan blowing gently on them will toughen up the stalks and put the light closer, they'll be fine
between 68 and 80 degrees seems to be optimal for my plants......70 is ok

thx for all the pointers..i have them heild up by toothpicks.so far so good no yellow leafs ether.just need to get a small fan
