PDS 1st Grow - OG Kush AF

Started seeing some signs of nutrient burn after being told I was using too strong a solution so I have backed off and started using a new feed schedule. This week the first pre-flowers showed up although I was unable to get a good picture this week. They are feminized seeds so I dont expect any males. OG Kush auto #1 - This has stretched out several more inches than its brother and sits right about 1 foot tall. Not sure if the extra height was caused by my topping of this plant before it went into flower. The backside does look a little light due to me cutting off new growth tips off the backside of both new stems. OG Kush auto #2 - This plant has only received LST and some light pruning. Last week I started working on pulling all the secondary branches outwards to reduce some of the crowding and this week it has filled out beautifully. It has stayed relatively short and has a very even top canopy with lots of bud sites.
