Looks like lack of nutes dude... My best suggestion would be to stick to one kind of food.. if your going to go with a 2 part, 3 part whatever.. stick to the same food for the entire grow. Second.. use a tried and tested feeding schedual.. whatever kind of food you get... use the feeding chart that tells you how much of each bottle to mix in at different times. All 2 part and 3 part foods have these charts available.. ask at your grow store or check the website... All plants need different things at different times throughout thier life cycle.. and by sticking to one food and one schedual you should notice a BIG improvement because your plants will be getting the correct type of nutes at the correct time! Good luck dude!
