Re: 600 watt Hydro Jack Herrer (GHS)
Okay I got a new PH meter. I didn't have any distilled water so I tested it with some vinegar. PH was 2.4 exactly what it should be, so I'm pretty confidant in the accuracy of the meter.
Base Water (Per 4 Gallons)
PH: 7.4
PPM: 305
Water + Nutrients
PH: 6.3
PPM: 970
Water + Nutrients + 1.5 teaspoons of PH down
PH: 6.0
PPM: 960
I guess with a PH of 6.3 my tap water was OK right out of the faucet. I am going to adjust the PH of 2 more gallons of water to 5.8 and add it to the nutrient mix. My plant seems to like a PPM (.5) of 820, which is oddly only 515 if I were using distilled water. That doesn't seem like much, I've seen post where people say they use 1200 in flowering. But since that's all she needs I'm not going poison her with extra nutrients. I'm very interested to see if she uses more nutrients with the water at a slightly lower PH.
I will be posting bud pictures in about half an hour.
A few days ago I wound up pruning a lot of her fan leaves. It makes me sad she isn't as bushy and lush as before. There was such an abundance of leaves, however, that it was not healthy for her any longer. The humidity in my home has been very high lately. So high, in fact, that I've been miserable. When she stretched her leaves started to rest against the sides of the tent and against one another. This led to some moisture retention that I deemed unsafe. I would rather have a smaller yield than no yield at all due to mold and rotting. I have learned to trust my instincts and mine were screaming at me to do something. I will never know if it was unnecessary but all the same I'm glad I did it - for my peace of mind!
The PH test strips I got indicated it. They actually appear to have worked rather well! Only .5 off for the nutrient solution and .2 off for the PH down!
I am going to see how much it drifts up over the next week. Next water change I may ADJUST THE PH to 5.8 to give a broader spectrum.

TheCapn said:You will know for sure when you get your PH meter. Your thinking is correct, but how do you know your water has a high alkalinity?
