Mostly white widow strain which I've always heard is good but maybe not these specific seeds, idk. There was likely some stress and such. One thing I noticed from these plants compared to the last is that I grew the last ones much much smaller, my biggest plant stem was only between quarter to half an inch thick, the stem on these are at least an inch and they're not done yet. So I was kinda thinking that taking a plant that has potential to be so big but only growing it small may have reduced it's potency, not sure if that's a thing. I am using a 200w mars hydro leds, they are supposed to be equivalent to 400w but I'm unsure, if that isn't accurate then maybe that would explain low potency although those first plants turned out fine under the same light. The first plants grew to their full size though considering they were autoflower and did their own thing so that's what makes me think that growing the first white widows to be smaller in size may have reduced their potency, that's just a theory though.
As I said my plants have dealt with some issues but for the most part solving issues is like shooting into the dark I've found since unless it has unique signs like Molybdenum deficiencies, it can be anything from over/under watering to not enough/too much of any of 100 things and if you add/reduce the wrong thing then you've got another issue entirely. I've got no issue with growing/cropping a plant but when it comes to their issues, if the PPM/PH is fine and the issues are still there then I'm entirely clueless.
