Indoor Meef's second attempt. 2x AutoWhite Widow LED grow.

[MeefChief]

Well, I just recently finished my first grow and I'm very eager to start my second. I've made a few slight changes this time. I'm going to experiment with a different feed schedule, light heights and try out air pots.

Setup:
-Gorilla 2'x4'x6'11"
-Two California Lightworks Solarflare 220 full cycle lights (165w running 18/6)
-Phresh Carbon Filter 4"
-TD100X 4" inline fan
-6" clip-on fan
-Bluelab PH pen
-Humidifier with humidistat
-5 gallon (15L roughly) air pots

Seeds:
- Two Dutch Passion AutoWhite Widow
-Happy Frog soil mixed with a recycled perlite substitute

Nutrients: Advanced
-Sensi Grow A+B
-Sensi Bloom A+B
-Voodoo Juice
-Bud Candy
-Big Bud
-Rhino Skin
-Sensizym
-Bud Factor X
-Overdrive
-B52

So are you going to PH? Looking forward to this one! The last batch you ran came out looking great!

What do you mean by am I going to pH?

Well, those nutes aren't meant to be PH'd. Buuut I noticed you are using a PH pen, so, I was wondering of you were going to PH.

Yeah.. I was running into an issue for some reason where my pH was 6.0-6.2 in flower. It was never steady for some reason. I would keep having to bump it up to 6.5-6.6

What was wrong with your PH? Bad lockout? I would avoid PH'n all together as it seems counter productive when those AN nutes are buffered to the max. Keep it simple, that's why people love the AN.

Maybe you're right. Idk man. I was having CalMag issues last run. @JohnnyShake

You may have been getting a salt buildup in your soil causing the drop in pH. When you feed, do give enough so 10-15 percent of what you pour in the top, comes out the bottom? This helps keep the naturally produced salts washed out of the medium and you get a more stable pH. With your problem occuring during flowering this seems like a real possability. I pH my feeds to 6.3 before feeding. I use Aluminum Sulfate to bring my initial medium pH down to 6.7 or so, and when I feed my pH will drop to 6.2 or 6.3, then slowly raise back up to 6.7 as things dry out. Not letting your medium dry out enough can prevent the pH from creeping back up too. I use AN nutes, but not the pH perfect lines. Very good nute line IMO. Just before I switch to flowering nutes I use FloroKleen to help get rid of the built up salts. Works good for me, alot of people do a flush at this stage for the same reason. Hope this helps with your next grow. Peace.
