Does anyone grow using water only, no nutes? I always get nute burn no matter what..

Make sure your using a new container to mix nutes with water.. Or make sure you disenfect the container well because any left over residual will throw your levels off.

I grew my plant outside for the first few months with no nutes at all. It grew in a pot and it only got rain water. I have been giving it some food for the past few weeks but I would say I didn't do anything to it for 3 months and it is green and healthy. The fan leaves on the way bottom are looking yellower but I heard that is normal.

yellow leaves arent norml. means the medium has no food left and is drawing fronm the plant now. i can keep mine green as long as i like, it is was needed.

i cant see the tap being high ppm and no ph to it. meaning a high ph also, i have 7.04 ph and 20 ppm tap here and of course you need to adjust the ph to suit what medium your in.

Wow your lucky that is super clean water. If I had that coming out of my tap I would drink it. Mine is about 450ppm at 6.6 ph, if I leave it out over night it evaporates to 7.2 ph and I lose 0 ppm.

If you mix even the smallest amount of fert with water like this, all the free ions already in the water will lock up any nutrients. It would be like if you added 10x' too much micro's, your fert will become poison.

People will mix back a small amount of tap because it usually adds Ca and Fe, which are commony low in indoor soil mix. Hydro of course just uses straight R/O. I am adding a little CalMg or Epsoms for my cocodirt, works better for me.

and that source isnt useable by the plant so it does nothing and blocks the good we use in almost every bottle of food there is out there. and in soil we barely need any of it. its more for coco not soil
both them links are sales pitches from a co tryin to sell you a filter. or food. adding back tap will kill microbes we want so is a waste of time doing that

the water rises cause the o2 is leaving the source. all water even bottled does this

yeah, i'll prolly jus switch to straight RO but then ill have to worry abut CalMag...neone know an organic CalMag? cause all i got is a huge bag of dolomite lime and i have a feeling that top dressing it or putting it in the water will compact the soil, it is a really fine dolo. though. But no, Medi 1 those were NOT outdoor plants i would just go and fetch creek water from a local creek and use it indoor but in the winter it would turn to ice or get too cold so we started using tap water on them. Those yields were all indoor... Neway one more thing, I usually let my teas sit in the growroom so they get nice and warm, problem is when i wake up the tea is usually a cool temp but then warms up under the lights after a couple hours...will this temp shift from warm to cool then back to warm kill microes?

You check your ppm? Are your meters calibrated? Looks like they are starving or your pH is off, locking out nutes.... 80-85 temps are perfect and never 90.

The point I was trying to make was about the Total Alkalinity of water turning the smallest amount of fertilizer into poison. No arguments here mixing back tap is a bad idea, but some people do it and that is why. Tap will only kill microbes if you dont let the chlorine evaporate, but its still garbage heavy salts in the water and not enough usable Ca. Total Alkalinity is very real I assure you its not a sales gimmick. Those sites just explain it well I thought, if you really read it through and dont pay attention to the sales pitches. Check the 4th paragraph down on the 2nd link it couldn't be any clearer than that. Alkalinity is the real issue, ph tricks alot of people this way. And as far as the problem posted by the OP, he wants to know why such a small amount of fert is frying his plants, that is the issue here right?

got a tds meter, my ppm was around 250 so now im switching it up to300-600 for veg and 600-900 for flower
