Ok. So I fed yesterday morning with my FF trio and Epsom salt. Thinking maybe I had a Magnesium deficiency. I have learned a valuable lesson here. And that is, to remove plants from grow lights before evaluating anything that has to do with color.
I still think something is up though.
I’ll likely post the same thing in the infirmary section of the forum, but for the sake of having this also documented in my grow diary, here it goes.
focusing on Big Kai.
I pulled her from the lights and had her under my 3500K LED downlights in my basement. Here is how she looked.
She looks much healthier overall than under my grow lights, here she is the plant on the RIGHT:
However, there are a few leaves at the bottom of the plant that are still pretty yellow. See below.
I was originally thinking the issue was Magnesium dif. However, there hasn’t been a major change after I added Epsom salt to my last water ~36 hours ago.
So, now I’m thinking, is it Nitrogen? Maybe. But, she’s 4-5 weeks into flower, so likely not as she should require less Nitrogen, and my FF trio includes Nitrogen.
Is she coming up on the end of flower and this is normal? Again, maybe. But it’s my first grow.
Is it iron? Again, maybe. But, pH has been solid and I feed with dechlorinated tap water. Which should have plenty of iron in it.
Thoughts?
If you’ve got any questions to help get to the bottom, I’m an open book.
