my friend followed a feeding guide, thinking he was mixing in 5l when the guy added to 10l water, so he doubled the feed line and had no problems he had good runoff which tookcare of salt buildups i guess but 4weeks and nothing bad,
advanced its hard to do wrong, with any need i never go above 1.4 evern with monsters its overkil i seen ppl run ec 2.5 like wtf
but nah i grew for over 10 years with ph and ec pens, i knwo my plants now i read them they tell me when they are hungry, visaversa
but with advanced ive thrown my pens away. its pointless tbh no point atall, once you hit 4lper litre u stay there u dont go over,
keep it simple
all growers here are experienced tho and all points are valid and good killer advice,
everyone has there method they liek and are entitled to it,
everyone i recomend thislien to though hasnt had a problem and grew killer weed withy no problems
its a good company email them and ask them anythign they wil reply fast
heres what they said to me when i quizzed them
cut soem bits with my questions and emails but self explanitary
''The way that the pHPerfect system works is that your pH range are opened wide up due to the additives we added to the base nutrient is good between 4.0 and 8.0. So do not touch the pH levels no matter what medium you are using.if you adjust it the pH up or down
it will fluctuate all the time, so let it do its own thing and just feed to the plants. If you have any concerns please call our Growers Support line and have a one on one with our growers support Team at

'pH is only one of the factors that control the mechanism by which the plants uptake nutrients, the components of the pHperfect formula include Humic and Fulvic acids, they act as chelators, they also contain amino acids which are also important in nutrient uptake control and Wet Betty (an organic wetting agent, together they create an environment that broadens the pH range within which the plants uptake nutrients, so adjusting pH is not that important''

In coco there is no need,
You should be feeding every day with good runoff, so even though you are feeding all the time, excess salts are also being “flushed” away in a sense.''
