Thanks for the link. I was thinkin about doing it on purpose to regain some foilage lost due to noob burn. (Nute burn) I'm willing to give it all the time she needs to get back to better health. Then again it may be too late and she may be ready to harvest. Not sure. I have read many threads and can't come to a solid conclusion. So many ppl say very different things. It's almost like religion lol
Pot growing is all opinions and experience for the most part, with a bit of guessing. That's why everyone answers will be different depending on the subjectiveness of the topic.
As far as regaining lost foliage, don't worry about it. Unless you have NO leaves, you have plenty of leaves.
Just keep doing what you were doing regardless of the light issue and you'll be fine.
If your growing an indica dominate strain, I like 75-80 days, sativas can go 90-100 days. Thats my personal preference, but if it helps give you a guideline, all the best. If your unsure if its ready for harvest, you can always clip a small nug off, dry it out for a couple days and smoke it. Won't taste the best but should help you figure out if it has the right high profile for you
