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?

Today I noticed 🍄mushrooms popping up with GiSCele. Does that matter? Are they🍄poisonous to girlies? Don’t bother me,but I dunno🤔. I recently started using 🦇 bat guano and have a feeling that’s what encouraged- kinda cool if I see Smurfette sunbathing on 👙🆒👍🏼

Grey leaf tips Booth plants are showing some kinds of burn and I am not sure if it is nutrient burn or light burn or if there is something missing. Looks a bit like MG deficite but shouldn't the plant take that from the soil in that state and age?

These three girls are all wilting and/or barely growing. I'd say over-watering except I've only been giving maybe a quart then waiting till the soil dries a little bit. Not too much tho. Could it be a nutrient problem already?

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.
