It's a form of mold from over watering. Scrape it off and let your medium dry up more before watering.

C02 and cannabis, is it a must?
C02 a must for your indoor grow? Is the light absorption through photosynthesis that significant on your yield? What’s your take? Experience w/ C02 activate bags or tanks?

USB Microscope vs 18x Macro-lense attachment
Is a USB microscope really necessary for checking on trichomes, or can a macro-lense attachment with 18x be sufficient? It seems like the USB microscope is a bit overkill.

Flushing
With flushing.. can I just feed her PhD water for the next week then harvest? Or is it best to put her in the bath and flush with like 3/5gallons of PhD water then harvest a week or so later?

In the left part of the first photo it shows how almost all look right now. All my girls are having 4-8 colas, ~40% of the bottom to up growth was removed. Should I remove almost all or all secondary shoots from the colas?Or should I let some on sides and remove the middle ones?

Harvest time?
This is my first grow. I was thinking about harvesting in the next couple of weeks. The trichomes look milky but none have turned amber yet. Thoughts? Should I wait longer? Any tips for harvest?

Accidentally poured 2mL of "Grow Big" into "Big Bloom" bottle.
I absentmindedly put 2mL of FF "grow big" directly into the bottle of"Big Bloom" (the murky one with bat guano). Is there going any type of reaction that will create products that would be unsafe for my plants? Haven't taken chemistry yet. Is it ruined?

In the dark
I have read that some growers give their plants 24-48 darkness before harvest. Is this BS or good practice ?

No budding on my LSD-25 auto flower
I don’t know what I’ve done wrong. My LSD-25 Autoflower is on week 10 and absolutely no buds at all. From what I’m reading it should have budded by now.

On week 10 of Autoflow, stop feeding about a week ago. buds are looking like they might be done but are still skinny. Was going to wait a day or two then do a day of darkness. does this sound about right? should I have feed longer?

LSD-25 not progressing
My LSD-25 is not progressing at all. I don't know what I can do to push-start it, the medium is coco coir and perlite mix and I did buffer with CalMag. Other plants are just fine. Might be the luck of the draw but I'm still being patient with her. Any thoughts on this?
