Hey Cronk! It appears I have missed your whole grow, but it looks like you are doing a great job with it! I've never grown photos, only autos.
I've grown 20 autos so far (3 going right now), and 2 of my plants wouldn't flower. I didn't have the chance to keep them in veg and switch them to 12-12 because my plants are all on different schedules. It really sucked taking them down, but I suppose it's part of the game.
I also just got on the Megacrop bandwagon. I bought the 21 lb bag because I have spent $55 on way worse things than a bag of nutrients that will last me years lol. I plan to get their other additives once I use all mine. I've been using it for about a week now and my plants seem happy.
While the seed companies say it's so many days from harvest, that's just a general guideline. I've had the same strain finish in 70 days on one plant and 86 days on another.
Great journal! Enjoy your harvest, and welcome to the world of autos lol.
