Looking good. Lanky Linda will make it. She is special.
You should always adjust your pH right before applying the mix to the soil. Adjusting the pH before adding nutes, or mixing it up the day before will not work because the solids in the water (if you are not using RO) and the nutes themselves will react against the water and the pH will change over time.Yep they are looking good and I could not be happier.
The only issue I seem to be having right now is the water ph I set the ph at 6.4 Two days later I recheck the ph and it’s back up to where it started. Around 7.2. I’m using standard hydroponics ph up and down.
My only real consern is that is my plants don’t dry out in 2 days is the ph in the soil going to be fluctuating as much as the water is. I guess next watering I should test the ph of the run off.

It is important to adjust your pH right before watering to 6.3 pH. At the moment you water, and saturate the soil from top to bottom, producing runoff, the pH of the water suspended in there vastly outweighs the soil, and the pH of the soil/water takes on the pH of the liquid you just applied. From that moment, the pH begins to drift, reacting to all it is in contact with, and it starts moving upward. This is why it is so important to adjust your pH to the low end of the scale, and let it drift through the entire usable range. You are thinking that you need to adjust something that does not need adjusting... the soil is designed to drift upwards. Testing your runoff pH is meaningless in soil... that measurement can not tell you anything about what is happening in the soil or what its base pH is. Just water correctly at 6.3 and the soil will take care of itself.
Now, if you had read how to properly water, you would know that the soil doesnt just dry out. The plant has to USE the water that you have applied... the vast majority does not simply evaporate. If you water correctly, to the point of runoff, you should not water again until the plant has used all of that water... all the way down to the bottom of the container. At the proper point of needing to water, your container will have no discernible water weight in it, and it will feel as light as a feather.
The pH of the soil is vastly misunderstood by many new gardeners. The soil is designed to have a base pH up near the high end of the 6.3-6.8 range. When it is dry, that is its pH. As the water level in your container begins to drop, the top part of the soil that has dried will be at that base pH, picking up nutrients that are mobile at that pH. As you go deeper into the container and the soil is just moist, the pH will be a combination of the base pH of the soil and the pH of the liquid... and since the liquid is so much heavier than the soil in that area, its pH is much more of an influence on what the actual pH in that area of the container will measure out to. Down at the bottom of the container where it is actually wet, the pH of the soil will be that of the liquid. This is physics... it can be no other way.
So, measuring the pH of the runoff tells you nothing about this varying pH from the top to the bottom of the container. The pH value of the runoff can be compared to the strength of coffee coming out of a percolator... the more grounds in the top, the stronger the coffee. The more soil your are filtering the water through to get runoff, the more solids it picks up on the way out. If you water to 2% runoff, the pH value and PPM value of that runoff will be one value, and if you water to 10% runoff, it will be another. There is no way to correlate this arbitrary value with the soil pH... it is a waste of time.
Are you planning on topping or fimming them. How many nodes do you have.
Nicely done. Looks great. They will bush out on you. Plants looking good. Magic
