Soil plant questions

[Oranjello]

I'm a first time grower. I bought some Diesel ryder seeds online and have planted them in Fox Farm's "happy frog" Soil. I have six seedlings so far, its been about a week and a half since germination. I have them all under a 150 HPS light. My question is when should i start to add the fox farm "Grow Big" nutrient? and how exactly should i test the ph of the soil afterward. i have a soil ph testing kit but im not quite sure what to test, the actual soil .... or just the run off water? Thanks for any comments

5-6 weeks and you should see them start to show signs of needing something more to eat. You can test the soil or run off me I do both just for the hell of it...

look online for the feeding schedule for foxfarm nutes. the guy at my hydro store gave one to me.
150 watt is pushin it for getting nice buds from 6 plants...i mean thats saying they are all female with 3 you might be able to swing it but you might not get the results you are expecting
