Droopy seedling
I only water as needed, making sure the soil is dry before I apply water. I do not soak the soil all crazy. I pour enough to where I know it’s getting to the bottom and stop. Should I not water this girl for a couple of days, she’s looking a little droopy after watering today.

Anyone have any ideas what this orange/brown mark could be? She’s in RQS easy boost and only been getting ph 6 water. I changed her pot yesterday, possibly something to do with that? Maybe different ph in new medium? Only one affected so far out of 3 plants. Thanks!

Help! Droopy leaves still
Should I go ahead and transplant to larger pots? These roots were long before I put them in these less than a gallon pots (all I had at the time) they’re still droopy after transplanting them on Friday. Afraid the pots too small for how long the roots are from the clone machine.

What's eating my plants?
It looks like there is a small bite mark on my plant. Presumably this is from an insect. It's an indoor grow but I'm using soil, melted snow water and my grow room is off the garage. Any thoughts on what this is and whether/how it should be dealt with? TIA.

Hey experts, I had some issues in week 7/8. See week 8 pics for additional clarification. Tri-lobbed leaves. Is this ruderalis genetics or am I experiencing re-veg due to stress? Deformed new growth, which is stunted and curled. Is this zinc issue due to pH or toxic salt buildup?

Sagging leaves
I have (2) 9 day old purple punch auto seedlings. They both have sagging leaves and were fine yesterday when I watered them. I think it’s because I have them in 2” peat pots inside solo cups. They get plenty of natural sun. They weren’t watered for 3 days before that.

Starting-to-Cook Deficiency?
I can’t seem to find issue. Look close at brown leaf spots. Rock solid variables with a tweak in the diet in week 7. Was the light cooking the life out of the canopy for last two weeks? Light was 8” and 1500-2000 PPFD before I yanked the top shelf out 3 days ago for distance.

Noticing slight brown spotting on a couple leaves accompanied by the tiniest little bit of yellowing/tip burn on the very tip edge, any advice?
Noticed today prior to feeding that i’ve started to get some slightly brown spots on 2-3 fan leaves and also noticed lots of tips starting to show the tiniest amount of burn on the tips. Dropped nutrients to about 80% dose and added some calmag. Any advice would be great.
