Black spots, leaf burn and lighting?

Hello all from down under,

New to this site and to growing indoors. I have some problems I need your help with please!

I have been growing outdoors for years but have decided to try my hand at indoors this year as I had some sensi seeds and want to keep the strain going.

Ok so here it is.

I have a super skunk plant which has been doing really well. She is in organic soil and under a 150w MH light. I feed her oz organic nutrient.

I have noticed for a few days that the leaf colour looks a little off at the ne sprouts but didn't think much of it. Then today I noticed about half a dozen leaves with black spots turning to completely dry area on leaves. This is only around the centre top of the plant. I am presuming it is burn from the light as the only other factor that has changed is possibly that she got a small amount of water which was meant for my outdoor babies (2 weeks from harvest) and had a small amount of Agave syrup in it for the final flash. But this has not affected the out door plants.

I can not attaches photo's for some reason, but am happy to forward them to ANYONE who can help, show ya some of my outdoor crops too ;). If you have any idea what is causing this please help me.


Thanks :)

Temp - 72 deg F

Please offer any help yo might have and I will try and figure why I can post pics.

Thanks
 
Hmmm tuff w/o pics but black spots usually show with either Potassium or Manganese deficiency. I'm not familiar with your nutes but what the N-P-K value of it may be a good place to start the investigation. :goodluck:
