What I am saying is learn the what and the why for doing things or not doing things.

No offence meat, but you have so much to learn and tbh, your first grow journal is really not the best place to learn everything and you should not really expect everyone to do all the thinking for you. Do some study, watch some videos - youtube is full of weed videos, but most importantly, try and learn the basics about growing plants. You do realise that cutting your leaves off can retard growth? No? These are the basic things you really need to know.
I can only speak for myself, but I am happy to pass on my knowledge and help, but not to teach everything about how plants function and grow.

What water are you using for res change?
Many suggest RO water, but the tap water is excellent where I live. It is, however, chlorinated, so I always draw off what I need and leave it a couple of days for the chlorine to degas and it then comes in about ph 6.5. After adding my nutes before filling, I only have to do the smallest of ph adjustment.
Do you test the ph after adding the nutes? If you have it anywhere between 5.8 and 6, I would suggest that is perfect as it should rise slightly over time and allow your calcium and magnesium to be absorbed.
It's not that these elements are being knocked out of solution, more that the plant can't absorb it till the ph rises above about 6. Although I've seen growers swear by a ph of less than 5.5, I'm dubious and my grow bears that out. That's why I start out with a low ph like 5.5 and let it slowly rise to at least 6.5 over time before I intervene. It's really not about a specific ph, but a range.
I was just reading throught your jounal the frozen bottle is just great that is clever thinking there. I am using distilled water and i never thought to check to see if it was chlorinated or not i just assumed it was not. I honestly havent been having much of a ph drift seems pretty constant. Was 6.0 when i checked and took a pic a bit ago. But you could be on to something do you think gallon bottled distilled water is chlorinated? The ph out right is around 5.5 straight from the bottle after nutes i usually only need to raise it slightly as the test liquid was a rusty red color saturday will be my first res change with my ph pen so i can get closer than a guess what number this color is lol. But is seems my new growth at res change always gets what looks like cal mag deficincy. Maybe that is chlorine. Im not sure maybe ill let my water sit out before using it. Or the company is lying about it being distilled water and it is just heavily filtered and chlorinated.
