I have five white rhinos and three swee tooth all outdoor anywhere from five and a half to eight and a half feet tall. they r in a soiless mix. I know i have made some mistakes on these no extra nutes in soiless mix i know they have a bad n deficiency which i'm trying to fix now do you think thats what this all could be a N def? This is my second year growing and last year had no problems at all but i didn't use a soiless mix. I use jacks 20-20-20 then switched to blossom booster 10-30-20. I don't know what to do if anyone knows what this is and how i can fix it let me know please tried flushing tried foliar feeding bought mollasses superthrive blood meal i just need to figure it out before they die thanks in advance for your help.
