HELP! Plants are under-curling and bottom leaves dying [PICS]

[DutchParadise]

I need some quick help to save my 2 of my outdoor plants which are doing bad recently.
I have 3 growing plants outside and 2 of them have recently are almost over a spider mite attack which i have been stopping using dish washer+water solution. This issue has already caused damage to the plants, but recently i noticed that the leaves have been curling down and the bottom leaves are all starting to die. Please tell me whats wrong and what causes them to curl down and die?? My third plant, planted about 2 weeks after the original 2 is already overgrown them.

Without any info, it looks like the plants are in straight worm castings with no perlite, and your lighting is insuffucient.

But if you copy and paste, then fill-out the appropriate troubleshooting form, we can likely give a better diagnosis. The link is in my signature.

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 (http://cannabis.com/growing/index.html)

Organic mould is just pH neutral soil. At the moment it is hard to get supplies for growing since during the month of August almost all stores are closed until September. Thanks for the advice and infomation and I've looked into what I should do.
I read the alcohol and water mix on a few sites online and said its a good way to quickly kill spidermites and does minimal damage cause it evaporates off rather fast.

Just wondering though what causes leaves to curl down though?

I've started 4 more plants a few days ago and will take in mind what you said.

Just wondering though what causes leaves to curl down though?
Possibly ph, overwatering or soil compaction. (no air to roots) Might not be able to trust the ph test strips, too.
