Also, running a 600 watt HID system, MH til flowering, then HPS. My second biggest TWA plant, is bushy, lush beautiful darker green, NO yellowing, watering and nutes, same is the bigger yellow tipped plant. Bigger plant shows female all over the place, 2nd plant shows a few female signs. These two plants look totally different. With a few yellow tips on JHA's, is it a light problem? Nute burn seems unlikely. Confused, naturally, as newbies are, lol. Thx.
