BigBudAutoMSNL Bloomplus1500 QBLED Coco

Oct 19th. I claim to be wk1 veg I've been using spray bottles for the weaker solution(and no call mag in it). When I bumped to higher dose I only watered a small area since it's a big pot(5gal) for a small plant(4"). Since I was not seeing any progression, I watered with a whole gallon to get some runoff and get rid of any potential salt build up from all the previous light feedings. I got very little runoff with very high EC. Next day or two once the coco was somewhat dry I did a water flush ph to 5.8. I have been feeding every other day with about ¾ to 1gal of mild veg solution.
