Weather and Less nutes!

Did anyone else have to use half of what was recomended with their outdoor plots this summer in the mid-west. I have 2 that are flourishing, 4 lowlifes just picked 2 at 60 days. letting other 2 go till end of month. It seems that when i use the scale provided by the company i start to get tip burn next day. I flush it neem it and ph test it and its fine in 2 days. I think the cool weather no rain and when it does it down pours for 3 days???? Out of 5 greenhouse white rhinos 4 died? or were eaten. I transplanted the last one to bucket and brought her home fed her, then in one quick blast it grew straight up 26in and started to flower with like 3 sets of nodes way at the top. I didnt even have a chance to top her cuz of the light change but it is flowering way at the top.
Im gonna attribute this to a weather year cuz the seeds i have from like 6gens all from my local area growers are doing just fine.
