That's a hard one to tell. It could either be mold or salt build up.

How much taller is she going to get? Every time I try to LST I end up supercropping or topping and I don't want to do that but I am running up against a space maximum.

Is the bud rot? What to do?
Is this bud rot? I found it on two bud sites so far on my big plant. What would you do? 1) Assuming it's rot or some other infection would you just harvest now? It's like 2-2.5 weeks early. 2) Wait one more week and see and risk spread?

Mould on seedling
This seed was late to spawn. Now it finally opened, even if it's quite short on the soil. I can see a fluff of mould just below the cotyledons. What should I do? Can I save it or do I risk contaminating the rest of the plants in the growbox?

7th week flowering mold problem. What can I do?
Hello everyone, in the last few weeks unfortunately I have eliminated some florets because a bit of mold has been created, I do not think it is real botrytis because if it was botrytis in 2-3 weeks it had to infect all the plants, it is a small percentage that I have eliminated .

Mold and Harvest time
Hey bros, take a look at the last Day 102 pics, mold... what do you think? Does not smell like it, comes from outside. Looks like a bunch of white pistils together. I've cut one of to examine further with the mic. I will update the pics later. Oh, and also, one more week to go?

Mouldy, webbed buds
The humidity was too high when I went away and now my buds are mouldy. Obviously I’m heart broken (mainly at my own stupidity because I should know better!) and I wondered if there was anything I can do to recover some of the crop. Can I wash? spray? Dry out…basically anything?!?

Possible mold issue
I've had a drastic change in smell... overnight. Smell went from very pungent to an earthy almost musty smell. Could this be a precursor to bud rot? Or is this sometimes normal? Humidity avg 50-55% during day and no higher than 65% at night with constant ventilation/circulation

Should I throw a net on her to limit her height or continue LST and leaf tucking? I’m siding with the latter but maybe it will help her in flowering as well if I spread her canopy under a net? Week 5 and showing pre flowering.
