If you mean when I switched them to flower; no reason. Just a newb trying to make seeds for the first time. I was recommended to flower the females out first and then introduce the males a week or so after in the future, which I’ll definitely give a try.
If you mean why am I withdrawing the males soon; the females have received copious amounts of pollen from what I’ve seen. I don’t see a need to keep feeding the males further if they’re job’s complete. These are small plants without many bud-sites.
“pH Perfect Technology” is what Advanced Nutrients’ has in all their lines, connoisseur included. I’m running the entire Connoisseur Master line, except for Rhino Skin (never bought it) and Bud Facto X (it spoiled). Their nutrient calculator can be found here. Here’s the chart it spews out:
And also a diagram that you can print:
Now that being said, I didn’t know I didn’t have to add additives to females producing seeds! 
The toxicity makes total sense too. Big Bud, B-52, and Nirvana all have high K values. I’ve dealt so much with deficiencies that it escaped my mind that it might be a toxicity. Thank you for your time and input.
Luckily they need watering, so I’m going to give them water (pH’ed to 5.8) and measure runoff.
