Help! Noob here, finally attempting my first grow after many years of wanting to try and I’m having several different symptoms. Two plants, almost 4 weeks from germination. On the first plant, older growth is having brown/yellowing issues, and suddenly this week there are silver/whitish spots showing up on some of the new growth (though I did get some water/nutes on a couple leaves, maybe that caused the marks?). Other plant looks better, but has a little bit of leaf curling/twisting happening. Using all General Hydroponics for the nutes. The Micro/Gro/Bloom trio and CalMag, along with Armor Si, Diamond Nectar, and Rapidstart for the roots. Am I crazy or do they not also look a bit underdeveloped for being almost a month old? Any help is greatly appreciated guys, thanks so much!
