Absolutely beautiful colours. Those leaves are almost black!
Cant wait to see the harvest! Why is this thread called "I failed"? Looks like you nailed it!
It almost looks like they were just injured. Handled too roughly or got scorched somehow. Full plant pictures to get the full perspective.
Also check out the website posted by Doug above
How are you reading ph? Double check the run off bc something tells me it's off. Cal mag issues go from bottom up so I'm assuming you've already lost the lower leaves.
The other leaves look super green so try increasing the cal mag and leaving out the feed next watering.
What size is the pot?
Yeah 12 hours or so darkness triggers the plant to start flowering. Revegging should be fine. Give it time.
And the Epsom salts is in regard to what I was talking about cal mag. Epsom salts are a type of magnesium. The mag in calmag. They work great. They're actually fantastic for tomatoes too...
Have you checked your ph? Could be causing those purple stems and possible nutrient lock out.
Since it's coco I have to ask - are you giving any calmag? If not, it's time.
I've personally had to add cal mag to every grow no matter the soil. Good news is that you'll know quickly if it was the issue as they bounce back decently with no new yellowing. Already yellowed leaves likely wont regreen but might.
So not coco. Make sure you're letting it completely dry out between waterings. The pot should be super light. Literally pick it up to test.
And definitely check that ph. The purple stems are a give away. Lots of posts on how to check and adjust Ph
You will never go back! So much better than playing around with the 12/12. So far super easy to grow the light cycle doesnt matter. You may even be able to get 2 harvests per year out on BC.
Yeah I'm in Canada also so I get it. I'm in ontario so it's even worse with our cold autumns. Made me switch to autoflower, which I couldn't recommend more btw
