Hi there I am about 23 days into veg and my girls are beautiful however I have noticed that since we fed them last there are tips that are yellow and some spots in like one leave of three of my five plants .. husband said it happened the night we fed them but I don't know I don't think there was any yellowing before that I check them constantly lol I'm definitely obsessed with my girls lol 1000 watt led 4x4x7 tent cheap organic soil and happy frog soil mix .. fox farm nutes ... they on 18/6 and have been for all 23 days.. I gave them Tuesday night fox farm big bloom 2tsps per gallon and 1tsp of grow big and didn't water them give days prior to that .. so not sure if they were hungry or if it's nuts burn or maybe a mag def? Please anyone that can help me I don't want that yellowing to get worse ...
