orange tips and ppm question

[Cong88]

Hi everyone im growin a northern light auto it about weeks old and the thing i dont understand it for the last 3 to 4 weeks everytime i check the ppm from the runoff it is the same as the input ppm or just the littlest bit lower than input does this mean the plant isnt really eating or is this normal, the plant looks fine but i dont know as this is my first grow another thing is just befor the auto went into flower all the leaves have got a small bit of bright orange colour right at the tip of the leaves they are not burnt looking or anything just the smallest bit of bright orange on the tip of every leaf anybody know what this could be??

Thank you for any advice you can give

@Cong88 The first question that comes to mind is your EC meter calibrated and a quality meter? The second is I don't use run-off information for anything. It is just not a reliable source of information. If you watch it all of the time you may be able to extrapolate something but I think it is a waste of time.

I would like to see pictures in regular day light (5000K) but what you are describing is called tip-burn. When I am growing a new strain (most of the time) I start my nutrients at 50% strength and increase 10% per week until I see a little bit of tip burn and then I back off 10%. Then I am feeding what that plant likes.

Growing in coco? If so and your runoff is less than 300ppm off from your input, you're in the zone. Under 200 is preferable.
As stated above, it sounds like you're right on the edge of too much, I'd drop the input ppm's by 200.

If you're not growing in coco, disregard what I said. :smoking:
