NEED HELP NEW MOTHER TO ME IS IT OK

I know exactly your problem bro. You are using General Hydroponics 3part nutrients. This system lacks Magniesium and calcium. Calmag or 1/4th tsp/gal epson salt will remedy this. As per overgrow.com. anyway. Overwatering is also a factor that cannot be overlooked. An NFT system such as yours that usually runs on a 78gph pump that was changed to a 250gph pump can overfill a resevoir that is clogged by huge bud plant roots and has water retention. Meaning that more water is pumped in than out per sec. Keeping the waterlevel higher than necessary. Its a film technique right. Not Nutrient Flood Technique. If Im wrong sombody please tell me. Hey Zandor!! Could you give your 2cents. Or Lama man 666
