Is this a calcium def?

**Little906** · 02-04-20, 09:58 AM

Good Morning! Ive been searching a lot on google and cant seem to lock an answer in place.

When she was growing there was no signs of stress through the veg period, although the growth was very fast.

Since flowering started ive noticed brown spot appear, the edges of the leaf start to die as shown in the pics, i think it could be cal/mag deficiency, what do you think it is? Have you had this issue before?

Temps -28/30
Humid - 65/70
Lights - 18/6
Nutes - sensi grow/bloom

Humidity is a tad high for flower bud.
Best try get some lights off pic so people can see it better

These spots, all over the plant or top or bottom? I've got same problem mainly top, new leaves which I think suggest Calcium, but phosphorous or potassium (can't remember which but both essential for flowering) defs look very similar and I do have the odd spot down on lower leaves.

I'm now certain mine is potassium, they are proper rounded brown spots, these, although we can't see properly until we get a decent pic, look more elongated marks. Badly need a light off pic.

Looks like your light is too close, and burning the plant. JMO
