I have been doing so much reading over the last couple of days as to what the problem i'm having could be. But everything I think I have found what it would be, I read something else that it could possibly be. Being the careful slow and steady guy I am, I have not rushed into trying to fix the problem and risked causing more serious harm.
I am not able to give to specific of information about the soil I am using and such unfortunately, but I will give as much as I can.
I am growing in DebCo organic potting soil, with pearlite and sulfate of potash added (not able to gibe NPK specifics.)
There is some Yates Dynamic Lifter organic slow release fertilizer pellets mixed in. (I'm thinking this is the base cause of my problem, although the NPK percentages in it are relatively low.)
The pots are 14mm and the babies have been in there for about 2 weeks now. They are 38 days from seed (give or take 2 days.)
Watering with boiled and cooled/rested tap water.
When I have done PH tsts of the soil it has shown be between a 6 and 7 rating. Although i'm questionable on the effectiveness of this as i'm using the dye and powder testing kit.
I have tested my water once with the same kit, and it showed a nice 6-7 reading, although I am really skeptical of the accuracy of the dye and powder used for water testing.
Also noteworthy is that a couple of times we had to water them with water straight from the tap, unrested and un boiled. Although this didn't seem to have any profound effects.
The plants are spending the days outside in the lovely warm Aussie summer sun, then coming inside at night going under fluro lights for the extra 4 or so hours needed to keep 18/6.
I know that my setup inside is really not optimal and I know it is causing some pest problems for me. But at the moment I really have no other choice.
Due to these pest problems (I have spotted a couple of white flies or thrips, not sure which and had a few webs strung between some leaves, I have also caught and killed a larger spidermite.)
I am not overly worried about this right now but we used some pyrethrum solution to try to deter the mites, it has possibly worked. But I made an error when applying this stuff which caused some problems.
It was about 1 and a half weeks ago that the pyrethrum solution was applied, through a spray bottle misting the whole plant and giving the top layer of soil a small spray also. My error was though that In the rush I used the manufactures instructions on dose and put 20ml to the liter of water which was way to strong. But I had thought that after a few foilar feedings of pure water that the negative effects of that had dispersed.
I am still watering only with water (staying organic here.) I plan to add some molasses in within the next week when I can go get some. I want to veg for the rest of this month and then go into flower. I think I will leave them in these pots until a week or two before flipping to 12/12 (or just leaving them outside in the greenhouse in this case,) then up pot again and let them settle before flowering.
Out of the 6 little ones we have going, 3 of them are still looking particularly healthy and 3 are showing symptoms of something. One has got really really bad in only about 5 days, it went from healthy as the others to detrimentally in need of help.
Here are pics I have got to show you guys.

I can get some more pics tomorrow if needed.
So thanks for reading through this if you have spent some time doing so, I appreciate all the help I can get, and hope that this thread can help someone else out.
I'm sure my problem/s are not to big, but with my one month of growing experience I think you guys will be able to lead me in a better direction.
(Sorry fo not using the template, but it was a bit confusing for me and I think I got all the information I needed to out to you guys in my own context. Sorry if it is an arduous read.)
