Is this Nutrient Burn or Light Burn?

I lowered light intensity, tried feeding with pure water no nutrients... cant understand why im having this rust coloration on my leaves! I'm thinking nitrogen or calcium, should I run some calimag? My EC/PH meters come in in a few days, gonna need some things to try!

So if it was nutes it would be starting from the tips/edges of the leaves.. so you can take that out of your worry list. You said you use well water..

If it was nute toxicity it would be browning at the tips/edges first, not the middle so cal mag would be your friend here since you can eliminate nute tox. You say you use well water. Do you have a water softener? Check the ppm of it when you get the meter. Could be hard water or ph is off. Even though you have never had this problem.

I started them actually with Distilled water all the way from seed until about a week ago I gave them some well water instead and fed them. Got my Milwaukee meter ill be doing some shit today, will report back!

Good looking plant
Thank you, I'm new to indoor, always done outdoor with no issue.

Use the directions.
Uh yeah I did... Poured 7ph solution and 4ph solution provided. I dip the probes into the solution and hit CAL, once it stops blinking you hit CFM. Seems to work with 7PH solution but when I do 4ph solution it says error and reports that I'm using the wrong solution? So much for buying a $120 meter... :wall:

Soak the probe tip in storage solution for a day maybe two and retry the calibration. Calibration errors are usually due to dirty probe tips. Good luck.

If not, return it.

Cigarz try not to over think the whole indoor outdoor grow. You are a experienced grower whether or not you have grown inside. You have a lot of knowledge. You dont get tht size and good looking of a plant from being a noob. So what I'm trying to say is everything you have done outside is the same as inside. Only difference is you get to control the environment in which your ladies grow and how much light she receives. Those are the 2 biggest things that you have cant control when doing a outside grow...

Ok so distilled is fine but just know that their is not a single ppm in distilled water so, she wont be getting anything from the water besides hydration. Are you in coco? I couldn't remember. Did you end up hitting he w the cal-mag?
