Pineapple Express Auto (First grow)

@HarbingerOfHarvests, thanks for your answer to my question. A little torn right now in what to do - my grow diary is a little deceiving because I've got 3 plants and this one with the problems is 2 weeks behind, so in the 3rd week of flower. I've hardly been feeding it as I thought I had an N2 overdose that I figured was down to overwatering and some wind burn(brown marks) So since then (probably 1.5 weeks ago) I've been feeding it a very low (0.5ml) dose and it wasnt until 2 days ago I started back up at 1ml. Do you still think this is too much? The yellowing is getting worse by the day and honestly I don't think they'll survive another week if I don't do something

@DrBuffy, Soil is a tricky monster.. Soil conditions are different given the different types. Some soils are Alkaline some are Acidic.. Some are very rich in micro nutrients. Some are poor. Your standard over the counter potting soil should have plenty of nutrients for your Cannabis. Instead of trying to take hold and change everything by what you are doing.. Lean towards the idea that maybe what you are adding is actually what is causing it. Plants tend to grow very well in potting soil.. And they tend to require nutrients when they outgrow there container or get large enough to intake all the available nutrients in the soil. Do you understand what I mean?... Think of your plant at a few weeks old.. Think about how soil there is vs. Root matter. The plants speak a language to us. We just have to learn to listen.. Lots of old ladies grow plenty of stuff in soil with just water and sunlight.. Again think about it :). Try adding or using just water for a few weeks.. Maybe use like 0.25 of bloom to be safe... But that's it don't use buffers or anything else. If you buffer down soil that is already on the acidic side.. This is worse for the plant then given plan old 7 ph water. If your soil is Peat Moss based like most soils then chances are it's on the acidic side of the scale already so need to "buffer" down. And maybe not weeks.. Try it for a few days.. like even a week see what happens.. See if she get hers balance back.
