Plants show good resistant and added the a/n hobbist bundle used voodoo juice only 7days at about 1/4ml per litre making sure that the total ppm of base neuts and additives dont get much over the chart in the pics but the roots just exploded wished i had bought the vodoo earlier but the they are expensive so couldn't but id say it does make it easier even tho there ph perfect never stayed at 5.7 id adjust by droping a drop of ph down straight into resoirvoir stop using citric acid it was just not worth the hassle didnt keep ph down long enough if you follow that feeding schedule should be ok with any neuts aslong as you follow chart i used the 3part but adjusted it according to that chart and used additives no more than 1ml per litre at final phases but tottal ppm didnt go over 1000ppm and thats 2 plants in the same resorvoir
