Wow. Where to begin...?

What is "organic mould", and are you using it straight? Is it properly composted? Would find a suitable potting soil with perlite, for soil aeration. Likely you are suffocating the roots.

With 2 plants in one container, at least one of 'em will lose the battle for rootspace. Possibly both. Especially during the flower stage, and double especially with atwo plants. One pot, one plant.

You can't properly use test strips on tinted water. (runoff water) The tinting skews the results. Why not use your tapwater?

Fertilizer sticks are unacceptable. Uneven distribution and release of nutrients. And, they dissolve quicker when warm, than when cool. Would do some research, and find an acceptable alternative as soon as possible. Fox Farms and Botanicare are fine examples...

Where did you learn to spray the alcohol:water mix on cannabis? Have you successfully done this before? A great way to kill the plants, is to kill the leaves. Alcohol is a good choice to accompolish this. For god's sake folks...try everything you spray on one leaf, before dousing the entire plant. Better to kill one leaf, then the whole crop.

I recommend you get real familiar with the Frequently Asked Questions page: Frequently Asked Questions page
