help! 5 day old hindu kush seedlings

I have 5 day old seedlings that seem to be starting to yellow from the middle of the tiny leaves.. temps at 77-82 fahrenheit.. moisture at aroun 35-45%... still just using water with ph around 5.8..

what could be the problem

it might be too much light...jus started some new ones and put under 600 watt...not a good idea...moved to 400 watts of t5 and now they are gravy

i think 6.5 ph level is IDEAL. but i dont think thats the problem! what kind of soil u got bro? what kind of lighting?

could it be the temperature change? I saw a picture in the plant problem thread that was probably the closest

How often do you water? Does the plant droop at all or is just a discoloring in the leaves?

weedaholic wants help but doesnt post pic or answer questions!

pics please.

sorry for the late replies. but I'm growing in rockwool, and it's just discoloring of the leaves, slight discoloring. the only thing I noticed was a temperature drop when the humidifier ran out of water and the heat jumped up. I water when needed try to keep the cubes not to wet and not to dry.

I usually post right before I go to sleep so there might be a while till I answer..

thx for the help

yeah and I don't have I camera yet
