Bud Problems

[valerie 43]

We have been growing for some time, and our last crops produced big fat buds. This crop is having problems. The have started out just fine buds were forming good then they just started to turn. The white hairs turned as if there done. They have alot of resin but the buds are so small compared to last crop. We though it was the cold and put heaters, thought it was humity still no luck. We use 1000 watt Hps and Hydroponic system. Please Help We would appriciate any sugestions.
Thank you. Blooming Idit

Is this the same strain you had good yields from last time.Not all strains produce good yields.Cool temps generally slow growth so lessened yields can be expected from.A slight ph difference in your hydro solution can increase or decrease uptake and effect yield as well.There is alot of variables that can cause lessened yields from the same strain,only you can answer that.Some strains will loose vigor with inbreeding,thus lessened yields.Is what ya need to do is make a list of every variable(re: temps,humidity,solution ph,nutrients,nutrient temps ect) and compare to the last grow,in essence a process of elimination to find the culprit.Thats why keeping records is a good idea.Good luck,Peace
