Day 16:
Firstly, thanks Faded187, for all of your help with the FIM information! I feel much more comfortable now.
Changed the res water today. I bumped up the nutes to 1/2 strength. I am using the feeding charts that Humboldt nutrients has on their site, so the doses increase every week according to that, but I am using those numbers and adjusting them to a percentage point. So today's res change went by the week 3 amounts on the schedule, cut to 1/2 strength. The amounts actually increased quite a bit more than 1/4 from the last res, because the amounts in the schedule increase weekly. So I hope I am working that right. I suppose we'll find out pretty quickly.
Here is a pic of the girls in my cabinet.
They seem to be much shorter than one would expect at 16 days. The growth seems to be on track otherwise. Lefty is a bit ahead in growth, and has some new leaf sets forming where the branches connect to the main stalk. I raised the lights up to around 2 feet above the plants to hopefully encourage some stretching. I would like them to start getting a bit taller, and anticipate a bunch of growth over the next 10 days. I have been keeping the lights really close, so that is most likely why they have stayed so short. But it's time to let them spread their wings! Time will tell.
Here is Lefty. She is the faster of the two plants so far. She is showing her 5th set of leaves, and is getting some growth in the crotches now. She will be left to grow naturally, but will be getting some LST in a week or so, depending on whether or not I can get her to start stretching upward.
Here is Righty. She is a bit behind, even though they both sprouted on the same day. She will be the plant I am going to FIM. I think this will be a pretty good experiment. I am basically going to FIM the plant that is ALREADY behind and see what happens. The other plant has more leaf sets, more undergrowth, and overall actually seems a bit more healthy to me, just based on growth and time.
I will be fimming her at the 4th node. I will do this sometime in the next 3 days. Basically, when I feel that the 4th set of leaves are big enough to get hold of and cut. But before the 5th set is any more than a tiny sprout.
If the FIM is successful, and I end up yielding more from Righty, I will most likely FIM the majority of my plants going forward.
I will detail the FIM when it happens.
Wish me luck!
