Hey guys, looking for some cat drench advice. I have two slurricanes about 30ish days into flower, I'm a dummy and forgot to note the date. I'm thinking they're ready for the cat, what do you all think? Btw they are different phenols, not sure if that makes a difference.
First one:
Second one:
You're good to go, Drogon.
In fact, you're a bit late, I'd say. I usually Cat later than most, and this is about the stage I hit them.
The nice part about a late Cat is watching the way the calyxes swell on those big buds. 
I doubt it. Basically, it's a timing thing. You need enough time for the 2 Cats, a water, and a couple GE/water cycles before the chop. For fast strains, that may not leave a lot of room. You're 30 days into bloom? So ... 30-40 days to go. That should be plenty.
The rule of thumb is that Cat drench in the early part of the window promotes denser buds and a faster finish. A late Cat can get better yield with the 10-12 week strains.
Be prepared to see some fast fading after the Cats, though. Yours look a little weak and you don't have much time to fix it first. But I had a lot of fade in my grows and learned not to be too concerned by it. The final product is usually better than good. It just makes me want to be a better grower.
What Graytail said.
I used to be so gung ho to apply the cat drench early.
I averaged around day 19 thru day 24.
As a result, my leafs would go start looking funky.
This round I am pushing the CD out to week 5/6.
Pics below were day 37.
Strain is Platinum Gorilla by In House Genetics.
That's just ridiculous!
