I have my plants under a 400 watt lamp, about three weeks into flowering in soil Using Jungle Juice 3-part Nutes. I feed/water them every tuesday alternating between plain water and feeding. I always let it sit out overnight. I may have accidently fed two rounds in a row because after feeding this week I saw some really good growth after the first day but now Im seeing this in areas of both my plants mostly near the bottom on littler leaves but seems to maybe be crawling up as I saw a larger fan leaf in the middle looking similar today. The leaves seem to yellow and the brown quickly and die off left to right or vice versa. I just cant remember, I usually pre mix so I know, but they looked liked they needed a feeding so I fed them. Please let me know what this looks like and what I can do to fix it. Thanks so much.
