What's Happening to my Glookies? Lower Growth Yellowing with Grey/Light Brown Spots.
Yellowing with grey/light brown spots occurring on the Glookies plants (starting from the tip of the leaf). I believe it may be due to the Fox Farm Ocean Forest soil mix but any advice or input on what is possibly happening is greatly appreciated. Fingers also fused together.

Please see the 2 photos marked in the diary. Is this a classic PK burn? Did a feed with no MegaCrop, no cal-mag, just PK boost at diluted dosage. The coppering and yellowing has come sudden. Leaves are crispy where burnt. I hear its easy to burn with PK boost. Did I do that?

Dark tips
it seems to me that the tips of the leaves have a very dark color, it looks like an excess of nitrogen but in three weeks I have never fertilized and the only additions to my biobizz light mix are a sprinkling of guano kalong and 10% of worm humus biobizz.

Starting to see small dark/black discolorations on the leaves. Since I don't know the genetics, I can't tell if it's prone to dark leaves. Could it be signs of anything else? Note: Started watering only using TopMax and ActiVera because of some possible Nitrogen toxicity
