1) Growing indoors (greenhouse)
2) Watering schedule = every 3 days, alternating 5-1-1 fish emulsion and 10-15-10 Schultz
3) 24/0 light cycle under 42" grow-fluorescents
4) Temp. stays around 75, humidity around 30%

The problem:

Only present on 2 of the 6 plants, one of my bigger, beefier plants is starting to get yellow spots on it's biggest leaves, and the cotyledons have turned yellow and are drooping at this point as well. Another plant I have has completely given up on life... Leaves are drooping to the point that they're touching the stem...


Now I have some 24-8-16 fert I was planning on switching to, but if it's nutrient burn I guess I shouldn't. Also, I know they need bigger pots, I was planning on getting that done today.

And sorry about shitty pictures, cell phone camera.

post new pics. cotyledons are supposed to fall off eventually. ANY FLOURESCENT BULB IS TO BE AT LEAST 2 inches from plant. ! i wish everyone would learn that.

Yeah, I couldn't have moved the tray out to take a picture... :roll:

And the concern was more at the second set of leaves there...

id say switch your tubes for 45 watt CFL Spiral bulbs... they are way better and more concentrated. you can grow a good amount with one per plant if u choose to flower a couple weeks early

o one more thing... your stems look really skinny for the height.. you need a small ocilating fan to promote stronger plants

Thats also from not enough light...their stretching therefore making the stems look like dental floss...take it from me, i had the same problem.

Yes, I know, I have a fan that's turned on when I'm not trying to take pictures with a shitty camera phone, and I'm planning on repotting them up to the first set of leaves to get rid of all the stretching they did when they were 1-2 weeks old.

My concerns were with the brown/yellow spots on the leaves and the completely dying plant that you're all ignoring... OBVIOUSLY it's not light/heat/air movement, because then it would be more than the 1 out of 6 plants that had a problem. I'm not an idiot, I understand they're stretching, I just don't know what the dying plant is about.

if there are black spots than it could be mold. If its yellow spots its it could be iron def. check the tds and ph lvls of your water and lower or raise it to 6.7-6.8
