Looks like it has similar symptoms to pH fluctuations. If it was my grow, I would check the pH of the water/food before and then check the run-off after watering. Happy Growing!👉😁👈

Discoloration bud leaves
Anybody know what this discoloration is? Humidity was a bit too high so I'm hoping not some type of mold. The affected buds did get quite a lot of wind and light, so it might be light- or windburn? Any help appreciated!

What is this deficiency?
They started off with some brown spots and progressed. Is this phosphorus? I have been feeding with .5-1ml of dyna grow bloom and 2ml of cal mag per gallon watering at about 6.3-4 ph. But i recalibrated my ph pen and did one water since.

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)

Deficiencies while in late flowering during flushing period
There is deficiency going on (looks like cal) she is an auto flowering strain in her 9th week and been flushed for a week now. Should I give her cal/mag and stop the flushing or is it too late to deal with that? She looks like she will be ready to chop in a week or so.

Brown spots on tips of some leaves
4 leaves affected on only one plant. All plants are receiving same feeding and are from same clones. Based on photo and googling it looks awfully lot like P deficiency? I'm still in vegetation phase though. I'm feeding with Advanced Hydroponics Grow + Bloom + Micro based on chart

Stickstoffüberschuss?
I have a problem with my auto that it's hardly growing in height, and there are spots on one leaf. But I have the feeling that the other leaves are also too dark? Maybe it's not growing anymore because of a nitrogen surplus? Should I water it without fertilizer for now?
