"Mix Pack" Auto Fast Buds

pretty bummed out the other 2 plants that are flowering in the same tent as these mixed autos both might have hermed on me so i had to chop them early. the 2 mixed autos are looking a little droopy / sad so i really hope they didn't get pollinated. we went on a trip to colorado this week and i didnt have anyone to watch the plants or water them but i figured they would be fine being as we were only gone 3.5 days. well when i got back they looked fine and i only had enough water for the mixed pack plants. i waited until morning for the banana pp and regular purple punch and then they both started feeling almost crunchy on top so i did some investigating and i found a few nanners . i chopped right away and am praying for the best. one of these has some copperish hue to the tips on the newer growth? im not sure what that means im seeing maybe too much iron? i really need to calibrate my ph pen so i can pay more attention to it. i have been getting disttilled water jugs so its usually at 7 and im assuming the nutrients bring it down some but i rarely check because i never trust if the pen is on or not lol. thinking about going organic to avoid dealing with ph at all.
