Pink Kush (Feminizied by Barneys Farm / My Second Grow ever / Organic)

Its Blossom Day 70 Today and i will Harvest them on coming Thursday on BD 75. The least Waterings i only flushed them to get a better Taste. As you can see i did cut the Headbud of the tallest one, they started to mold and luckily i recognized it early, i wondered last Week why the Leafs turned yellow and brown and why they were dried out, they really were crispy and i pulled them some days before and they came out easily and on one of those i have seen mold plus the day after i have seen that there was a light brown Area instead of a fresh green Area so that was the point i decided to cut it down. My mistake was to havent put down something under the tallest Plant also, so she couldnt drink the Drain, usually i pull it out some Hours after the Waterings but the last times i havent done it because i werent at Home to the times before the Lights shut off. So she got the Drainage Water with all the Nutrientsalts of all Plants, so i guess she did mold due to be in a State of being Overnutrient. Also the tallest one started to get purple on some Buds and some Leafs of the midsized too. What do you think how the weight of the Yield will turn out, let me know.
