It looks pretty bad for your little green friend, unfortunately. So that his passing isn't for vain, now might be a time to get few items together to keep this from happening again. A 60 watt light isn't going to help too much...but every little bit helps and 2 of them are much better than nothing. With the immanent passing, I would go out and get a bag of good, quality potting soil, like Miracle Grow or another name brand with a good reputation. I use
Promix, but just about any quality growing medium that won't get hard (like yard or garden soil tends to do after a while) and has good drainage. I'd get a bigger pot to grow it in, since the last one was sort of small...the more root area they have, the better/faster they will grow. Pop a seed or find a clone and put it in the new pot, watering it prior to planting and once again, lightly, once in the ground. Stay on top of the water because small pots dry out quickly and can cause problems with young plants. I can't recommend how much or often to water using the LEDs that you have, since I don't know how quickly they will dry out. You don't want the medium to be dry, but not soaked, either. Damp is best.
Sorry for the rant. I just don't want to see you fail again when it is actually pretty easy to have a good grow as long as you have a good growing medium, plenty of light (maybe most important), water, and regular $10 fertilizer/nutes. The hardest thing is leaving them alone and having patience. It's like watching paint dry, but patience will reward you well if you don't try to overthink the grow. I learned 35 + years ago, using a 1000w Metal Halide light,
Promix, 6 gallon buckets, and generic fertilizer. I stuck with the recipe and have never had a problem since, other than bugs or issues that I created. I guess it can be like playing golf... the more you think about it, the worse you perform. Just letting things go will reward you in the end. It can be super simple or it can be complex depending on what and how you grow it. Start easy and simple. If you need help, I'm more than happy to teach you what I know.
