Purple leaves Hi Guys, some of my leaves are developing a purple shine. I guess its because of a nutrient deficiency but im not 100% sure. Im watering every week once with 0,4-0,5ml of Bio Grow. What should I do now?

Another round of Name That Deficiency 5 weeks into flower and this plant seems to be the problem child but she’s also the one showing the most growth. PH is 6 on her, was originally 6.2 but was having a manganese deficiency so went down to 6.0. Gave 3/4 of recommended nutrients in last feeding. Not sure what to do.

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.
