Yellowing leaves almost half way through flower in GH. Organic grow. (lots of pics)

So I'm growing 14 plants total. 12 are in a pots in a greenhouse, and two are in the ground outside basking in the full glory of the sun.

So I've been feeding these plants Bountea, with some LK, and Molasses. Everything is going pretty well, except in the last week or so the plants have been yellowing up.. In particular my Purple Trainwreck, which is getter all yellow. The other plants are starting to show as well. Orginally I thought it was just a normal deal, the plant was ditching less effeicent leaves etc, as it goes into hardcore flower mod.

The reason I'm not so sure is tha tit's still spreading, and the two plants outside, which get fed waaay less than the GH ones are showing no signs of yellowing at all.

So I'm just wondering if I should throw some nitrogen into their tea.. I don't want to overdue it though, don't want it to get confused with the surplus nitrogen and start to grow my veg shit.

Anyway, the strains are, Blueberry the big bushy plant outside, Master P is the other one outside, the LST plant with severe yellowing on the bottom is The Purple Trainwreck, the rest are a mix of Grape Ape, and a strain called Hollywood.

Any help would be appreciated! Thanks~

Hmm, no one has any idea? I'm pretty certain of the issue, but some confirmation or discussion would be nice. Please help out! Don't be shy, just respond if you look at this post!

This is normal. Your plants are sucking the nutes out of the old fan leaves.

Yah, I think the same thing, buit then I look at the plants outside and wonder, How come the ones in the ground aren't doing the same? On the LST plant, there are some lower branches with flowers(probably should ahve clipped them completely) that are yellowing up as well.

I suppose the ones in the ground though can pretty much find whatever nute they want, aren't constrained by the soil in a pot.

The Train Wreck is by far the worst, the others seem pretty okay.

Thanks for the response!

My plants outside are doing the same, old fan leaves turning yellow.

Hmm, at what point should this stop? I did not have this issue last year, but last year I didn't go the organic route.
