It's definitely a Cal/Mag deficiency if you did not give her cal/mag nutes.
Ph fluctuation also cause this problem, so the next time feed her with cal/mag and make sure the right ph for coco which is around 5.5-5.8

Leaves turning yellow from the bottom upMy older plants leaves are turning yellow from the bottom up. Its probably a nitrogen deficiency I think, I read that its common for plants in late flower but this one just shot its first pistils. What would be the smartest thing to do to combat this? Thx

Magnesium Deficiency ? How can I fix it ?got a little deficiency (maybe burned? but I think not).
I'm pretty sure it's magnesium's deficiency, it happens after a flushing. I added 2 times the last 2 weeks a little bit of CalMag (BioBizz, but ive bought it 2 years ago, maybe it doesn't work well idk).

Is this light burn?I have discoloring on the top leaves of the plant. It started today and I think it has to do with the lights, so I‘ve turned them down and moved them up about 1-2 inches. Can anyone confirm if I’ve diagnosed it correctly and if not what the issue might be. Thanks.

I need advice on what to do with this plant. I flushed her a bit and I think nutrient burining is not showing on new growth, what ppm should i feed her?I watered only last week and mesaured runoff ppm and ph. Water was 350 ppm and 6 ph and runooff was 700ppm and 6.7 ph. Before when i fed her with 850 ppm runoff was 1500 ppm.
I would continue to water only but there was a lot of yellow and pale leaves so gave her light dosage.5y ago
