GSC Auto coco/perlite

Every time i open up after daylight i get a gentle whiff of a slightly sweet welcome 😊, Noticing her bulking up on a daily basis and shes a thirsty girl, Bud sites are all looking great , I read somewhere that gsc loves the nutes , I can confirm this the more boost i add the better she gets , may well give her a pk high soon and put it away , however and this is my fault , Ive had a bit of windburn below or nute burn ,rectified the fan regardless its only affected 4 bottom leaves if it gets worse I will lay off the boost a tad , My run off had been high in veg , me again i think not pre-soaking with correct ph 💩 , so this is my first auto and cocoa so could be worse😎 , any suggestions on a replacement for canna boost , and cannazyme most appreciated😀 . 2 caramelicious at 4 days so will start diary next monday👍
