Hi mate, looks like your plant may need a feed. She will start to kill off less important older growth. RAISe her EC a little and see if this helps. Good luck and happy growing

Black spots?
Is this a deficiency, nutrient burn, or disease, growing in MG soil, recovering from overwatering as well.

Leaves are gray/brown and curl down. HELP!
Im a first time grower and I cannot figure what’s wrong. I’ve been feeding it Calmag and Grow from Biobizz since last week. 1 ml/l grow, 0,8ml/l calmag. PH of water + nutes is 6.3. The soil is coco and pearlite. Did I give it too many nutrients? Did I overwatater?

calcium deficiency?
I've notice some brown spot on one of the 3 Fat Bananas. I think it is due to calcium deficiency. I am not sure though, as this is the only plant of the 11 in the garden, which are having this issue . What do you think?

So closing week 7 now and my 4AM are showing signs of deficiencies again. I watered(with nutes) ph'd around 7 past few times and the runoff has still been ~5.9, indicating acidic soil(nute lockout)?At this point, you think it's best I just flush with plain tap water(ph ~7.7)?

Leaves looking f’d?
What’s happening with these leaves? It started last week and has spread. Only the leaves in the middle under the light. Week five of flower. Was using the same nutes and strengths since flowering started at 6ph. Upped the strength this week to see if it would fix and it got worse

Leaf discoloration. 5 weeks old
I transplanted these girls 2 days ago and have started them on a new nutrition. I’ve noticed some discoloration on one of the leaves today almost sure it’s the nutrients. Can someone help me figure the best thing to feed my plants? Thank you (nutrition diagram on my first diary)

2 out of 5 plants are showing signs of nutrient burn? Soil grow
Hi, I am seeing clear signs of nutrient burn but only on 2 out of 5 plants. I feed them organic nutrients, following the chart that was provided by BioBizz. Why are they still showing burned leaves? I watered them thoroughly until the runoff was clear. But leaves keep burning.😦
