Hi
Problem: leaf curling / twisting, leaf discolouration which seems to be starting from top down. Brown spots on leaves.
Medium/grow method: Coco / perlite (ecothrive). Fabric pots
Feed: and supplements used: Biobizz range (Calmag, Bloom, Grow, Top max, Bioheaven, algamic & activera)
water source: Supermarket bottled drinking water (ph 6.2 at source)
Strain/age: Dutch Passion Banana Blaze / 6 weeks
light used: 100w Led board - generic fixture
Climate: 24c / 75% rh
Additional info: this is new in the past couple of days, I snipped a bit of the bushiness about 2 days ago, since then I have noticed these problems, which are rapidly increasing.
When I feed I do mix all the mentioned nutes together (not sure if I shoulddo that) and then at the end i ph the water/nutrient mix to around 6. My runoff is measuring around 6.7. I suspect manganese def but I am unsure when looking at other pictures as there seems to be a few symptoms going on here.
Up until I defoliated a bit she was looking fairly happy, maybe a tad on the dark green side but was growing well. Last feed was plain water with a drop of calmag which I ph’d at 5.5 trying to bring the runoff ph down. Day before yesterday and there were none of these problems except maybe a little bit of leaf curl which I had put down to heat.
