Very slow growth and dying leaves - Please help me save my grow

First I'd like to thanks everyone who took the time to read this thread.

So, here.is.the.problem:

I'm growing a Somango and a Super Silver Haze since mid-April, but the growth has been remarkably slow since the beginning. Initially, the Somango was really stuck, then, when it was showing some signs of recovery, the SSH started showing some very abnormal growth, and when it became vigorous, the Somango displayed problems again, this time with leaves slowly necrosing and dying. The plants were alternating problems like that until recently, when they finnaly started to show some strenght and consistency.

All of a sudden, about one week ago, the situation turned: the growth of both plants virtually stopped and their lower leaves began necrosing and dying (the Somango never got rid of the problem, but it was improving a lot), only that this time the necrosis seems to be moving a lot faster - every time I open my grow the situation is worse and I see new affected leaves. If it continues like that I think both plants will die soon.

I'm growing in a wardrobe (about 1.7x0.8x0.5 meters HxLxW) with CFL lamps (160W), and using soil (50% perlite and 50% peat), in 7 liter fabric pots. The plants are receiving a weekly dose of Bio-Grow and Bio-Heaven, about 2.5 ml of each (initially it was 1.5 ml, though last week I lowered the dose again). They also received some Magnesium Sulphate, but I cease the application about two weeks ago. I wonder if the decrease of the ferts dose (and the cessation of the Magnesium Sulphate) is somewhat responsible for the plants getting worse, but I did that because the growth was already stopping and I thought that maybe the problem was overfertilization...

After the initial difficulties, I came to the conclusion that the PH of the water I was using with the plants may be causing the problem, so I bought a PH pen and, when I finally managed to use it (like 20 days ago - it took a long time to arrive), it was indicating 7.5! After correcting the PH of the water to 6.2 and flushing the plants, the initial response was satisfactory, but soon things became very ugly, and here I am. My last attempt of solving the problem was flushing the plants again 3 days ago, but it only seemed to accelerate the deterioration.

Some people will tell me to throw the plants away and startover because they're weak and will not develop in a satisfactory manner. Unfortunately, thats not an option now since those were my last two seeds and I will not be able to obtain more for some long time. Well, I think thats all. Thanks again and I will appreciate a lot any comments and suggestions!

Your deficient. Your feeding program sucks because of what you are using. Neither product is useful alone or even together without some other fertilizer.

Buy some GH or Advanced Nutrients.

Thanks, I will try to find it. You mean geographically? I live in South America, my city has a mild temperature (average of 26ºC), and now we are in winter.

Coco A and B will work beautifully. Can buy off eBay and that will do veg and bloom.
Thanks for the advice! Unfortunately, Canna fertilizers are not available in my region and if I bought them through eBay it will take too long to arrive... Are there any other ferts that.you recommend?

Mirecal grow is another good one. But the best I've used is canna coco A B. I use that through the whole grow and when they start to flower I add big bud it's defently worth buying and pk13-4 for the last two weeks. Puts on massive weight o the buds. I have no problem getting 8-12oz a plant.

And flush your plants with just water. Feed them only PH 6.5 water for a week. That should bring them back to life and don't give them heavy doses of fert just yet. There still a bit young.
