5weeks

Here I have blue cheese 5th week veg which I've grown from fem seeds, 450W LED 16/8 Humidifier set to 60% Fan Extractor with charcoal filter Air intake at the bottom Heater set to 22C I have just repotted in miracle grow soil which has all the nutes in for 6 weeks so I water every 2 days...

I'm not too sure which one it is. I'm assuming it's all of them. 5th weeks in hydro. Sour Diesel. 300W LED (140 true w). 5 gallon bucket. Hydro with clay pebbles. I can't figure it out if it is magnesium problem due to the pictures and or potassium problem. There seems to be a lot of problems...
