Any more Oxine info? I just got some and I’m curious if it’s best to mix up a batch for every use? Or is it best to mix up a stock solution and then dilute that into the reservoir? Also what frequency do you guys use it at? I’m trying to get away from buying UC roots all the time.

Well my water tests came back and it’s boron. I suspect my issue was worse than most because I use a lot of humidification. So essentially a boron mist was being sprayed on the plants as well as the root zone. The only other thing in my water tests was sodium at 25ppm which is a little high...

I got my leaf tissue analysis back. Everything was normal except phosphorus was low, which can maybe be expected cause plants are in super early veg. As I suspected boron was way high though. The leaf sample tested out at 236 ppm. Most of the ranges for normal growth I could find were...

Yeah I’m leaning on the side of nutrient. The environment is fairly controlled. I have a 20” maxfan exhaust controlling temps, and a huge mainland mart ultrasonic humidifier adding moisture during the day cycle. And then a huge dri eaz dehumidifier to keep humidity in check during the night cycle.

Yeah it was quite the job putting it all together. The RO system is up on a hill by the holding tank. The water is terrible out of the well. Ph 9, tds is about 400, lots of iron, sodium, all kinds of minerals. The bummer is the well right across the street is excellent water coming out at 50...

Here’s a pic of the first part of my water filtration.

I’ve never heard of toxicity’s happening after RO filtration either so you could very well be right about me chasing my tail there.

Oh the pic of the healthy plants is similar lighting. It’s just a pic with lights on. the pics of sick plants I took with lights off just so you can get a better idea of the colors without getting all bleached out. I got out the lumen meter yesterday just to make sure they weren’t getting to...

Here’s a pic of plants at other site with 1ml per gallon calmag and 1/2 ml per gallon veg a and b. ppm is at 200.

Ok, yeah I see what you’re saying about the ratio. Maybe I’ll just dial back my calmag to 1 ml per gallon. And then keep my veg a and b at 1/2 ml per gallon.

Nope, yesterday I drained my water tank and filled it from a neighbors well. It’s a way better well than mine. 50ppm out of the tap. I figure I’ll drain my system and fill with the neighbors water and that will rule out something weird going on with the water like boron toxicity or petrochemical...

Whatcha guys think about a boron toxicity? Is that barking up the wrong tree? Pre RO filter my boron level is 1.92 Mg/L which is kind of on the high side..

Man I’m just not sure I should go that high. I feel like if all my other RDWC rooms are at the 180-280 ppm range and the plants are really healthy in the 1-2’ range why should this room have such different nutrient needs? I could def be missing something and you guys could explain it to me...

You think I should be higher than 270 ppm on 700 scale with how big they are right now?

The plants are just past clone stage so I think a high ppm would lock them out. Are you in DWC roscoe? Or are you in a hydroton based grow?
