Nutrient excess or deficiency? - Red Poisen auto

[Markus]

G’day all,

Just trying to diagnose my Red Poison. This is it here.

 

I always tend to get a little tip burn but this seems abit different. The leaves seem a little burnt along the edges of the leaves also. I only seemed to notice it after a flush but it may have been like this prior and I haven’t noticed. I wouldn’t have thought deficiency as I don’t really go about half strength nutes.

 

I have added another light in the tent so have a 900w mars hydro led and a 400w mars hydro led in my 1x1x2m. That is the only thing I’ve changed and I have the lights 1-1.5 foot away.

 

Currently using canna terra professional medium with canna Flores nutrients at 1/3 to 1/2 strength.

 

Does anybody have any ideas? I’ve had a good search but a lot of nutrient deficiencies seem to look very similar to excess nutrient symptoms.

 

Thanks in advance for any help.

I have also just noticed another plant with a different issue. Could this be a cal or mag deficiency?

Cheers!

I’ve had similar but more in a bigger blotch n yellow, don’t know why , never knew what it was but was only the odd leaf here n there , I won’t worry unless it starts to get out of control

If u having been adding cal/mag through the grow it wouldn’t hurt to give it some

I was usually do 1 feed a week or 2 depending what I see

Check the underside of your leaves for a possible pest infestation.... sometimes these dots appear where the nutes are being sucked out by mites or the like.
