Soil growing tends not to need pH adjustment. I am growing in Happy Frog with rice hulls as my only amendment. (I am also using Fox Farm nutrients.) My water's pH is 7.6. I'm just finishing the second week after the flip and my plants seem to be doing well with the water I'm using. Rice hulls help with drainage and decompose in the soil, which improves the soil (in my opinion).
It looks to me like you've done well. You should be able to harvest a crop. Now is a good time to start planning your next grow, making note of the things you could do better. I suggest filling your pots fuller, because the closer the soil is to the top, the better the air flow. Another suggestion is not to make more than one change at a time, because it's much easier to understand the effect(s) of the change.
Watering these plants is a common problem. They do surprisingly well in dry soil. I am using a soil moisture meter for the first time this grow. The first picture shows the meter. The second picture shows as much of the plant as I could get in the picture. In the picture, you'll see that the plant is doing well even though the moisture meter show that the soil is very dry. Notice also that the probe is pushed into the soil as far as it can go. That's about 10 inches and about 3/4 of the way to the bottom.
I find using these meters (that only cost about $10 on Amazon) has been very helpful. I measure the soil moisture once or twice a day. When the meter is low and the plants looks like they could use some water, I give them water (and nutrients, too, if it's time to feed). When I water, I add water until there's some runoff, but I haven't been measuring the runoff. When I see it start to drip, I stop adding water. I have the pots on plant elevators to help drainage and to aerate the bottom of the pot, as well as keep the soil warmer. Also, I recommend watering slowly to give the soil time to soak up the water. Adding water quickly can cause much of it to go straight through the soil without being absorbed.

The pictures were taken a week ago. Here's what the plant looks like today.
