beginner grow

Wow, been chasing my arse on these babies, obviously not all 8 ball, but thats all I am focussing on for this diary, I may add further dairies, but tbh the photos and the chat would be the same, needless to say, they are growing slowly, they are all either hybrid or indica, which I know from research are short and bushy, which is cool as I have 9 in my 1m tent. I think I managed to correct my light and nutrient issues over the past few weeks and started to LST. The main stalks on my plants are about 20mm thick and the root systems are poking out of the new pots I put them in a few weeks ago, I did state them in cloth bags, but.... couldn't monitor run off as the bag was retaining too much liquid, as my medium is clay pebbles and coco the water I do give them seems to just run straight through, I have had to water at 250ml twice a day when I choose to feed, watering twice a week, once with PH balanced and once with feed. I have been adding calmag at a rate of 2ml per litre when I do feed, on top of coco A and B. I have my carbon filter attached to my external fan and if I leave this off there is soooo much moisture in my tent, its almost raining, so I have to keep my fan on permanently, as well as my tower fan to help strengthen the plants, the result of that is the average temperature is around 20deg.
