you guys are funny. purple has nothing to do with in or outdoors. when we see it outside or with colder temps it measns its stopped chloraphyll production and is a weeker pot being that is the main growth to thwem needing that. ya you need to sober up cause you contradict yourself through the whole poist. no run off yes run off....lol
and to mc purp. you need to learn more before saying we are wrong., you know more than a nute manufacurer on how to use???? i did mention i worked for one didnt i..thats funny to say ph dont matter.,the ph window has nothing to do with the water, has to do if the nutes or what elements had been chelated. and that is way to expensive to do all nutes and nobody does it. run off tells us nothing????...whjat is the ph and ec of a run off do then. just to look at????
i may not know everyhting on nutrient mixing and so on but all you people that say no ph need to read more and have your stuff tested to show how week it is not using ph.
to the other dood, yes you ened run off and the amount depends on how much rpoot mass is in there. if not the ph will deffinatly drop out and become defficient and get burns.
