Eurogrow - Super Gold Auto

How you test soil and on second day after watering ??? If it's cheap 5£ Amazon stick in soil reader - forget it, it shows how fat milk is ;)))) Your grow is more soiless , like ProMix, they love 6.0-6.2 pH then. If you give good dry out and then watering cycles ( I grew for two years in similar mix, they need more soil attitude than soiless ) - you pH will naturally balance out. Try to make some run off when water, put dry new and CLEAN plate under pot to collect run off and measure then your pH and PPM or EC. if you are very close to what you put - you are PRO and will smoke loads of ... But if readings from in and out different - you have issues ... All the Best !
