This is my first time. I am using black magic soil and a hlg 300l rspec light. I have a tent coming but has not arrived yet. I soaked seeds for 5 days and then planted and took 2 days for them to break soil. Going good now but both cheese plants seem to have stubby leaves with brown i hope it shows in th pic. The rest seem ok but are greenest around veins. Like i said this is my first grow any thoughts are appreciated. I have been giving a cup pf wster in a 2 inch diametet around plants every 3 days. This was my 2nd time watering
