New indoor grower

Well I have done a little growing outdoors but my first attempt at indoor gardening is now happening. Here is a pic of one of my outdoor grows. It has been a few years that I have grown at all. So follow me along. Here is a shot of one of my 11 babies. only 2 are bought seed the other 9 are ones I found over the last 2 years in Dank, from buddies. Would find one or two seeds in pounds. They are 8 days old in the picture and are currently 10 days old. I'm using promix, with extra perlite and vermiculite. I was a little late getting my lime so I added a tablespoon to a gallon and have been watering with that mixture until I transplant to bigger pots which I will be using the same mix as above but with added lime and espoma organic planttone. Currently using 240 watts of mixed flouro's and have a 150 watt HPS too. I will be purchasing a bigger watt light soon in the future. My litmus paper is showing a PH of around 6.5. Any and all questions or help will be appreciated. Thanks. Mainesmoker

Watching...

The two bought seeds are a fem shark widow and the other is a Mandala #1. I have some lemon kush, big bud, sour d, and blue goo that came from dispensary smoke. All suggestions welcome. Thanks for looking

This is the most recent pic I have 2 of 11 that have begun to take on a little discoloration, they are different strains. Temp is around 78 in the grow area. Any ideas on what it may be. Do I need to be concerned. What can I do to fix it or do I need to? Thanks Mainesmoker.

Anybody got any ideas on this discoloration.....well I know you all do just is anyone looking is the question LOL

For some reason things are going down hill. I need some help to identify this. I'm not sure what is going on. its only 1 plant but one of my favorite strains (outdoors). I don't want the others to do the same. I have been searching but can't find any solutions other than possible bugs but I don't see any of any kind
