I will attempt to not be "a negative person", but often critiquing the grow of a new grower does involve not positive stuff. But keep in mind that everything we tell you is aimed at getting your grow to be the best that it can. LOL--you don't need to like me, but I do often have good advise.
First of all, if you are looking for constructive criticism, we could really use more information about your grow--size of tent, type and size of light, ventilation set up, type of medium (be specific), temperatures, RH, nutrients (if any), etc, etc. The more info you can give us the better.
You have a lot of stretch in the plants. This means that there is a lot of space between the branches. This is an undesirable thing as it gives you less bud sites. This is generally because of inadequate light or the light being too far away. It looks as if you may have an HID light, if so, adequate light may not be the problem, the distance from the plants may be the cause. They are also quite small for their age. Plants that are 2 months old should be substantially taller and bushier and ready to flower and you are quite a ways from that.
You need a ventilation system set up--not only to help control heat, but plants need a continual supply of fresh air all the time the lights are on for proper photosynthesis. This is accomplished with a good quality centrifuge type exhaust fan. You also need an oscillating fan to move the air around in the tent.
Like multi mentioned, your soil looks not right--too much bark material for one. Few if any soils are good enough to plant in without being amended. There are some good soil recipes in the Organic Section. Starting with a good soil is quite important.
Which will bring us to food...feeding the correct nutrients for the phase the plant is in is important, too. Plants need different nutrients during different phases of the plant's life. I also recommend nutrients formulated for cannabis. PH is important because the plant can only uptake nutrients at certain pH levels.
This is a hobby that takes a certain investment of time, money, energy, and love, but it also takes knowledge. Cannabis is a high energy plant and has quite specific needs--not like growing tomatoes. There are links to several good beginner growing books here in the Beginner Forum. They are a bit out of date, but have the basics.
