PH?

[Texassativa]

I have some AK-48 nirvana plants growing strong. They have never had any PH adjusted water. From seedling to now. The plants are about three weeks old from seed. They have been topped several times. I fert with a mix of beer, dish soap, Floor ammonia, karo suger syrup, superthrive, seaweed extract, and Medina hastaGro 6-12-6. I sure have read alot on PH being a real big deal. So when are my plants gonna' take a dive? The soil is a mix of Texans humas, shprom peat, perlite, doloimite lime, blood and bone meal. Water is straight tap water @7-8ph. The light is 400watt MH. The new light green growth at the tips have been seen on plants that were ph'd adjusted. Lights are on a 18hour day. So, again, why is the ph issue not being an issue?

The lime in your mix is buffering what you put in.Do you test your soils pH regularly?.....I would.

NOPE, never checked crap...They speak for themselves. I only used about a 1/4 cup dolo per five gal soil.

hmmmm.well looking very good sir!

Well that's the point of using dolomite lime, you don't have to check anything, you just feed and forget it.
The humates involved in an organic grow will also help with uptake, humic and fulvic acids will also keep things in check and are a product of an active soil.
Water quality is a factor here and what type of ammendments also come into play, some can whack the ph out.

So I dialed the soil in? I have used this soil mix on some other grows. Everytime I put nasty chemicals in the water to ph adjust, the other plants showed a ph shift problem. Don't, "fix it till it's broke".....I'am not gonna' use ph'd water, till she shows signs of needing it. And then, it will be other things adjusted before I slam some ph down in the water.

Yes dude you have it dialed in from the looks of it.
If you feel you need to adjust ph than use something natural like Apple cider vinegar, it is organic and will break down over time.
I measure the ph when I am feeding later in flowering, i like a soil ph that is a little more acidic ~6.2 in flowering, in veg a slightly higher soil ph is great.
The true test of a soil mix is flowering as alot of elements are being mobilized and processed in the soil web, you don't need to adjust the ph but measuring the ph of what you feed is good info to keep around in case of problems later on.
