Yellow leaf tops

Hey, first of all thanks for the answer.

Nothern Lights:
Plant 1 is looking great and dont have any yellow tips anymore, the plant is around 1,2m tall and is forming Buds everywhere.
Plant 2 never had yellow tips or brown parts and grows really good forming buds everywhere.

Green Gelato:
Plant 3 have yellow tips and and a lot of them, but she is in flower and has the biggest buds of all and a lot of them.
Plant 4 never had yellow tips or brown parts and is always growing well.
Plant 5 is looking really really bad, she is in flower as well butleafs are curling and they are really yellow already, also brown parts are showing.

I know that i overfed them, it is my first try and i never planted anything before. When i saw the first yellow tips 18 days after germination, i thought it may be a deficit because people told me that. Thats why i gave them a compost tea and 1 week later 1 top dressing. I know that i made the problem worse with that now.

What do you mean with i should not PH the water down? My tap water has a PH of 8, when i notice that the PH of the soil is to high i go down a little bit with the PH. i watered with a PH of 5.8 and the runoff has a PH of around 7, dosnt that tell me that the PH of the Soil is even higher? Like 7-7.5
and what else to do when your soils PH is to high exept for water with a low PH?

I used a light mix from a really good company in Europe and added worm humus and a 3/3/5 organic pre mix (Too much) so it is not really homemade soil and other peole do the same with great results and they also start with compost teas after like 4 weeks,
i simply had put to much worm humus and pre mix in the soil from the beginning and made thing worse with adding that compost tea and top dressing to early and belive me im not doing that mistake in the future.

I think that the plants will survive that, only plant 5 is worring me.
No master is falling from the sky, sooner or later you will make mistakes when you never grown before, you will only get better from that.

I wouldn't say that going from pH 8 to 5.8 is a little bit. 5.8 is about as low a pH as a grower wants to go and it's really used more for hydro, not soil. You have to remember that whatever you're using to lower your pH, this chemical is coming into contact with your roots. If anything, a runoff of 7 tells you that your soil pH is lower than 7, but your altering the pH of your water so it's hard to tell. You shouldn't worry about it anyway. It sounds like your keeping your soil constantly wet which isn't good either. Testing runoff is pretty pointless as it always confuses the grower. pH water down isn't usually necessary in soil. pH testing the runoff only tells you the pH of the runoff. It doesn't tell you the pH of the soil. The two aren't one and the same.
Nutrient level in water or soil causes the pH value. If you over fert your soil, no pH adjusted water will change that. A one time flush of non-pH adjusted water is a good idea in an attempt to flush out the nutrient, but then you also flush good things out and cause the soil to remain wet for a longer period. Soil needs a wet/dry cycle to allow oxygen to the roots. That liquid seaweed you're using probably isn't necessary.

Ok i seem to understand it a little bit more, because i have the space and possiblities to make the SuperSoil you talked about, im think about do it.
I checked recipies from High Time magazine and decided to start now so i can use it for the next grow.
I hope that everything goes fine the next time.

But i would still love to know why nearly every youtuber and organic reports tell someone to PH the water down for your ladies.
It just dosnt feel right to give my plants water with a PH of 8.

You might be right about pH 8 however you really should get better info than what's on the web, unless it's from a university. Find a plant scientist and see if they will answer you on the issue. And ask them "If I need to get my pH down, what do I use and what number do I shoot for?" 5.8 is too low for soil. The problem with using message boards and youtube is bad info spreads like wildfire on the internet. If it sounds good to people, they keep repeating it not knowing they are doing the wrong thing. People have the attitude of, if it sounds right it must be right. This is what happens when the uneducated communicate with each other. It gets taken as gospel. Believe half of what you see and none of what you hear.
Remember that what you're trying to do is build an environment that mimics mother nature. She doesn't force-feed anything. She doesn't adjust pH just because she can. Learn to work within her methods. Growers can't control everything. That's the beauty to Subcool's supersoil. He was a bottle feeder for years until he realized that he kept ruining the crop. He needed another solution and tried making supersoil. In doing so, he allowed bacteria over two months to break the granular ferts down to a molecular level that plants can absorb, which is what nature does. It worked. It's a hot soil, so just put it in the bottom 2/3rds or bottom half of a container. Put Roots soil or similar on top. Water when dry. Nature will work for you if you let it. The grow shops tends to be a waste of your money.
