5 week flowering issue

Running out of nitrogen. Nitrogen is a portable nutrient and the plant can suck it out of some leaves to put it into new growth.

Either the happy frog got exhausted and you didn't add any vegetative fertilizer or there is nutrient lock out due to an imbalance of some sort.

Pretty much the same thing happening to my girls at the moment.

Number one: double check your pH is correct. Bad pH will trigger nutrient lockout.
If your pH is correct then feed nitrogen-based nutrients. That's the first number when you see something like 3-5-4 on the label of fertilizer.
If your pH is incorrect you have to fix that first.

So yeah I checked my ph a few times and it was good. So I use a dose of cal-mag each time I feed. So the cal-mag is 2-0-0. So do you think I should use more nitrogen than that?

That rating is a ratio of the three main nutrients, but has nothing to do with quantity of nitrogen being supplied to the plant. It's just there to tell you that there's some in there and what it is relative to others. And cal mag isn't supposed to actually be a fertilizer, it's supposed to be calcium and magnesium which ends up with the ratio of those elements in minor amounts.

So anyway, yes, you need nitrogen, and no I'm not telling you what to buy. I just went out and bought some random crap which I don't necessarily recommend. On the other hand I just added some Epsom salts for the sulfur and magnesium so hopefully mine will green up a bit as well.
