Help, what are those weird yellow spots in late veg?
Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid. Checked the whole bud, but no insects. My other ideas are mold or stress from the light?

PM covered plant sentenced to death - What would you do?
I'm about to destroy this plant. Each branch has heavy PM despite having ample airflow. I suspect due to the lack of direct sunshine, but I'm sure it's spread to other plants which will also be destroyed. Is there anything I can do to salvage? What would you do? Thanks!

Mycelium or Fungus - Too much Part 2
I am seeing a ton of mycelium on all of my autopots. Because I have a bottom feed system, it is hard to keep my top medium wet without getting mold. Is this going to effect my end result if I do not do anything about this? Should I leave it alone or put sand on it? Thanks all

Bleu (largest of the 3 plants) is ~14 days behind the other 2. Is such a variance in size & rate of maturation common when growing from seed? Does LST/HST amplify the differences between phenotypes? She's so tall I'm worried about light stress. Should I reduce the light schedule?

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?

Algae on top soil
I have noticed some green algae growing on the top soil of my seedling. is that a good or bad thing? I am thinking its too humid or something. Or is it the Mycorrhizae in the soil mix.

White spots on lower branches
So this last week a few lower branches developed white spots that seem to cause deformation. Is this some kind of mold and do I need to do something about it? I’m worried it will stress if I let it be. Thanks in advance!

Seedlings are leggy and in a tray under the dome. Dome is cracked open. Using a T5 Reflector. Light is as close to dome as it can go. I have a Viparspectra 900W (R900) LED with a Veg and Flower mode. Env con good. Should I get these leggy bastards under my stronger grow light?
