No nutrients, and the light is a 400watt mh in a cooltube and gives off like no heat. Temps are only like 78 at the hottest pointswell either you put nutrients into the plant already and they are burning it, or the lighting is way too hot and burning it. What are you using for lighting and have you places nutes on it>??
I see what you are talking about , are you misting with water ? , i feel its just rooting , taking longer than the other , a seedlings first 2 sets of leaves are very tough , they normally just dump off and die , nute or soil burn would do just that"burn" , light heat stress would see the leaves droop down and maybe curl , my feeling is that it will be fine , and you have no choice but to wait, try giving it a double dose of dark period if your running 18/6 light cycle , this may boost root growth....good luckView attachment 1825020View attachment 1825021Check it out now. It doesnt look very healthy to me especially compared to my other plants. The leaves are almost turning white and its just losing color
You can't see it to well on camera but the color diffrence is huge between those two
Your plants are colour blind.your colored blind.
Thats a good sign , keep it moist , and its also good you buried it deeper , root riot cubes are awesome , but when you plant them to close to the top the stem can sometimes struggle later on in flower, this is good practice....By the way its already having the roots poke out of the rockwool cube it just hasnt reached the res yet
The roots of any plant will always branch out in search of water.well its in a 10 inch netpot so its probably gunna take a while before it reaches the res. I didnt have any water in the res though all this time, i didnt know having water under it will encourage it to find the water.
