Indoor Leaves keep yellowing

Can you be more specific about your soil? Is it a brand name? The basic nutrients, are they slow release?

That's a pretty broad range on your pH and depending on what the run off is reading, could be the cause of your issues. You may also be watering a bit too often. Cannabis plants like to go through wet/dry cycles. The best way to know when to water is to get a feel for your pots when they are almost dry. Only water when they feel that way. When you water, make sure to give enough so that about 10-15% runs out the bottom of the pots. Collect and test the pH of that run off water and let us know what that reading is. The more accurate you can be with those pH readings the better we can help you.

Muddy, Blue and namvet25 are on the case. You have the best of the best helping you now. Listen to what they say and you'll be golden.

Welcome to AFN GoodVibes. It looks like you've got lots of information to get your ladies back on the path to health, just remember that when it comes to fixing issues in canna slow is smooth and smooth is fast. A correct action late is better than an incorrect one on time. Good luck!

The soil is mixed with nutrients, and they are slow-release as far as i can make out. It should be decent quality soil, and it is bought at a plant shop.
i will try getting the readings for the run off water, my problem is that i dont have my own PH-meter yet, i am borrowing a friends a few times a week to measure the water.

and Blue, i didnt know that i would have to start at that low a dose, but fortunately they havent gotten much at this point, so thank you for pointing that out before it became a bigger problem

Autos can be nutrient sensitive and in general only require about 1/2 the nutrients that photo sensitive plants like. They also don't like "hot" soil mixes, ones with a lot of nutrients already in the mix, or ones that contain slow release nutrients. It's very possible that the people in your grow shop are not aware of this, so sold you a product that may be good for photo plants, but not for autos. I would suggest you only give them plain water, pHed to 6.5 the next feeding, no nutrients. Capture and test the run off and let us know what the readings are.

i have just made a test of the runoff water still in the tray, and it came out at 6,2-6,3. and for the next feeding i will do as you suggest and use 6,5 plain water no nutrients.

Most grow shops in my area have no clue about autoflowers. Even the nutrient companies info is not really as good when it comes to autos. There are still growers that have the old impression of autos being not as good as photo-sensitive cannabis. The good thing about AFN is that you are in the right place for info on autos and photos. Go slow and a wet/dry cycle is one of the best ways to keep you girls healthy. Easy on the nutrients, especially if your soil is "hot". Muddy is right about just giving them plain pHed 6.5 range water for the time being.

Your gonna make big and small mistakes as you get growing under your belt. Just keep it simple.

Hmmm this sounds so familiar to my first battle with time release nutes hehe it became a game of chasing the lockup dragon lol! It's probably great soil for garden plants, but I just learned the expensive and hard way lol that autoflower cannabis is really picky about soil. It will take awhile and some money, but if you can make the eventual switch to organic soil mixes, you'll have some relief and happier plants just my two cents, don't take it too seriously

The soil i'm using is advertised for normal garden plants, so i kinda learned my lesson on this one. But as you say, i expected to make some mistakes, this being my first grow and all, and so far i feel i've learned from these mistakes, and they shouldnt be a problem in future grows

You sound like you know your soil, is there any brand you would suggest, or a website you have faith in? I would like to get the right soil next time
