Sup everyone, first time grower and poster here wondering if you guys could help with identifying a problem with my babies. There almost 2 weeks old, SWC grow,under 3 CFLs, and nutes were supplied by guy I bought box from. I'm thinking it's nute burn. The box is 2ft tall not very wide but ventilated. Also how much veg time is recommend for a box the size that I have? (photos incoming on iPad have to figure out how to upload)
