Damn this thread blew up!! I love my Vipar 300W! And I just ordered a 450w for the next go around. Maybe one day I can grow up and have a cool advertiser logo next to my avatar.
I'll go cob eventually. For now and for my own purposes the spectra does just fine. This is my first go and I have 4 plants in a perpetual set up. For 2 you will be fine with the 300 but I wish I had bought the 450 in my situation.
I'm not the best at determining deficiencies so a little help is a appreciated. This is my White Widow in her 4th week of flower. She is in ocean forest soil and has been receiving fox farm nutes once a week at 3/4 strength. She is under a 300W LED light about 18 inches from canopy. I have...

Have you guys experienced light burn with the light being about a foot from the top of the canopy? I'm seeing a paling of top leaves. I was worried about mag deficiency but I'm not sure
Oh is exactly 6.5 and that action has already been done about 4 days ago. I just added some compost tea of mollasses and bat guano (0-5-0) which should help, we will see.
