All the fan leaves over the past two weeks turned yellow.From what I have seen that is normal.I waited till they were all but dead to pull them.My next grow I will be a little more aggressive with the nutrients especially when it comes time to flower.Being my first time I was a little hesitant when it came to feeding.Thats probably why they turned so rapidly due to lack of enough nutrients causing the plant to reach within for nutrition .I also had problems with the ph and heat witch could have contributed as well.From what I have seen thought the post in this site its a never ending learning experience:thumbsup:,if that makes since.It can only get better!
