no treat a half of liter of water and add the equivelant of nutes test the ph at every stage the point to this test is to determine if your plant is causing the ph swings. we know 2 things for a fact now your water has much calcium in it wich raises the ph. and your nutes have buffers in them too stabilize it a bit but its not enough . now we need to make sure your plants doesn't have any part on raising the ph in my case that was the case i did the test and the test water was stable but the one on the bucket was going higher day by day when i had the rain water i had more tolerance but with the tap water had 0 tolerance the ph was just keep rising.
When I add nutes, pH drops, but then comes back to natural waters pH. My nutes have something to keep pH stable, and it is doing that. Problem is with adjusting pH to correct levels
no no
Do you want me to add nutes into untreated water?
The funny thing was after I have cut the holes 
I managed to find out that in my country I cant get no uniseals, so I had to think of other way for fixing pipes into buckets. For the holes I used this https://i.ebayimg.com/00/s/MTEwMFgxMTAw/z/9zEAAOSwzgRWwfKy/$_35.JPG And it worked perfectly
that will help ya
But anyway, I've noticed that my lamp sides except mid has some sort of fog. I got concerned, cause I thought it might have affect the plant grow. And it actually was a big issue there, because once I cleaned the glass from the inside, my plants showed some strong signs of happy :> I think it will translate in faster growth now. Or maybe it is just coinsidence and my plants just finished recovering from all the stress I've caused them and starting to grow by their own now:> 
your ladies seem very happy and bushy i estimate fat yields
wow man your clever the hack with the thermoelectric module is briliant i sure will have this hack in mind for my next sativa grow oops gave a hint there
And also I think my ladies are already mature for blooming, please find image below. Im starting my transitioning this week, going to reduce day time by one hour every day this week, then on some point going to introduce girls with full lights on, then change the res with bloom nutes and off we go into full bloom next week. 
My main focus is other girls, and my second grow. Hopefully it will be stress free grow
you get a cola if you veg for 1 day A ROOTED CLONE wich even my clones that you consider them small were much bigger than that seedling i only veged them for a week. it needs at least 2 weeks in veg to be what you want it to be you need roots to go into flower and that little fella ain't have any. all it has is some tiny hairs to pool minimum amount of nutes and lots of water. pout it in a pot with perlite throw it in a box with a 40w cfl and 1/4 nutes feeds wait 2 more weeks after that you can place the root ball in a bucket with 1/4 nutes 10ml3% peroxide per 10l and a bubbler to get rid of all the perlite and place it under the led do 1 res clean each day for 3 days after that you can add it to the rdwc and bloom it with the other girls it will be a fat cola trust me.Yeah, I'm also thinking about going into bloom the most natural way possible. About full day/night of lights off, I've read that someone is doing that, so I was just wondering, but if you say to not do it, I will trust ya man.
Little fella is getting same nute amount as others since its in RDWC. I can't lower nutes just for little girl right there, cause bigger girls will be sad. I would really love to take out JB out of there, but I will keep it with others, it will be my test. I've seen people veg like for 3 days, and get one full cola of buds, and I will be fine by that
