Road too master cannabis~endless grow

Hey pep! It was a bit quiet here again due to my health,but now there is a New update,i have myfirst skunk in the flowering and the next ones to follow soon.The white widow begins to train flowers they should now at week 3-4 but I'm not sure I did not pay attention this time The strawberry sour diesel honestly make me a bit worried the leaves are getting brighter and look almost yellowish they turn purple in some places, I hope the Main shoot still swell in the next few weeks,i'm worried that i May have fertilized too much or too little...I have the last few time because of it only whit water poured but it does not seems to get netter, so I fertilize again and hope that it will last until week 16
