Am I in vegetative stage ?

Hey there, yes you're in veg. However, without more info in your diary entry it's hard to answer Some of you questions. Like what type of plant you're growing. Auto, fem or regular photo. Strain, type of light, etc...Autos are more sensitive than the others, and wouldn't require that light intensity starting out. With a 600w light at 11-12 inches, I would think it would burn up. Moreover, with an auto you'd probably do better starting out at about your 3rd week with around 25% of the recommended amount of nutes. Great nutrient. choice though☺️ you probably don't want to be using bloom stage nutes at all right now either. To much phosphorus and potassium for a young girl. With fems or photos you might be ok with that much light, but I start my girls out with low intensity, and gradually increase as they mature giving them full intensity shortly as they go into preflower. I a actually started my autos out at 30" with a 210w light at 25%, and didn't start nutes till like the end of week 2 at about 25%. I'm no expert either, but there are a lot more knowledgeable growers in the GD family that you can learn from. I would suggest taking a little time to enter more info into your diary. At the end of the day, the info you get for the time you put into your diary is a great payoff.😉 Hope these thoughts, and suggestions help. Happy growing, and welcome to GD!☺️
