I cant correct something when I have no idea what the problem is. Yellowing just means something is wrong. Im not a horticulturist?..to figure out what it may be. From what I read one shouldn't even have problems this early! lol. I learnt that gardening is not for me..certainly not mj! lol. Too hard to grow indoors for me
It was a fun ride..i learnt a bit in the past 6 weeks.
OK then.
You are right. Just chuck it out the door. No reason in wasting electricity.
Or put it outside and do its thing.
We all had to learn dude. One little yellow seedling and you give up.
How old are you? Do you quit everything so easy if it doesn't work out?
Read some of the sticky threads. The threads that stay at the top in the newbie and indoor sections.
It will most likely be fine and grow out of it.
If you change your mind, hit me up.
