Hey,
You're looking at harmless salt buildup as the the water evaporates from the fabric.
No bid deal, rinse it away if you're concerned, but it shouldnt harm anything.
Cheers,

I believe this is just a build up of minerals from your nutrient solution and nothing to be too concerned with. Best to make sure your fabric pot is not sitting in any run off water for long periods of time. Best of luck! 😼

At week 5 of flowering, I've read guides but all strains are diff. Does it look like it's time to start flushing 2 weeks and then chop?I have 4 different strains in my tent with different needs. Next time, probably keep it to one or two strains.
Does it look like time to start flushing the plants in the pictures? Having never done this, I don't know how long I can let them fatten and how to time it. Thoughts?

Pre-Flower(?): What should I consider?These are stigmas, right? This being the first sign of pre-flower, is there anything I need to do/change right now (nutrients, etc.). I'm still performing very light LST to manage the canopy -- Is that OK, or is now the time to stop all LST? Thank you :)
