Tent is running low 70s. Soil measures 68°. My water measures 58°! Should I buy an aquarium heater? Just bumped up the thermostat in the tent. We will see what it measures in the morning.
You want the pH closer to 6.5 and I've never seen GH tell people not to pH their nutrients. Not all plants run the same pH so adjustments have to be made. Also, following their recommended dosages is usually way too hot for cannabis.

Says it right there in the soil growing tips. I must admit, I was doubtful. Either way, how can I get the ph down in the soil now that the plant is in there? Usually, they say to add amendments before potting. The ph on the nutes is very low, around 4. I assume the ph lowers temporarily when feeding, but it always goes back up to seven.

That's not GH (like you said in the first post) that's GO.
It doesn't say "don't adjust," it says not "necessary" but that's retarded since diff plants need diff pH. I'd still test the pH after you mix a batch, let it sit for a while and then adjust to 6.5. You want the leachate to come out about 6.5 too and THAT is done by amending the soil. so it matches your desired pH.

Going over the plants tonight with the loupe and found some hitchhikers, so off to the store tomorrow for some neem oil. Otherwise, I've been ph-ing the nutes and water to the best of my ability, but no change to the racing stripes so far. Plants are still growing and flowers coming in. I'm realizing the limits of my drop and vial ph test kit, hard to judge colors with the nutes added, and will pick up a digital pen type tester tomorrow along with the neem oil.

No, I won't. The mites seem to be concentrated on one plant so far. Hopefully, I can get them under control soon. If not, are there other options I can use later?
End of week 3. Max height 28" Average height 24+" Light is positioned 12" above average height, and 18" above canopy. Sprayed twice for mites so far, alternating between Mighty Bomb and Azamax. Mites are still there, but few and far between. I will be spraying once again, tonight before bed. Been ph-ing the nutrients and water to low to mid sixes. Soil reliably tests at 7, both before and after watering/nutes. Runoff tests within one point of what I pour in. Still no change to the racing stripes, although the plants look healthy otherwise and have been growing steadily. Cold dry weather here has enabled the mites, I'm sure. I altered fan schedule, turned up the thermostat one notch, and added free standing water in the tent to increase the humidity. Humidity bottomed out at 22% earlier this week, but alterations have created 50% average with a daytime temp of 75°and 70° nights. Lots of flower action at every level of the plants. Debating the removal of lower buds. Any opinions on that?
I've heard good things about Azamax. Pyrethrum is another option but even that might not be good late in flower either. Some miticides are allegedly safe after 1 week but I'd say 3-4 weeks before harvest is as late as I'd go with most. AVID is one I'd avoid completely.
Low humidity is good for spider mites, high humidity is bad for them.
