Please help! Contorted, darker green and slightly shiny leaves with spots.Do you think this looks like a nitrogen toxicity issue? Is it likely because I made a mistake using mainstream potting mix with slow release fertiliser in it? If so, will a flush or multiple flushes help, or should I transplant to better quality, organic soil? Thanks in advance!Week 3

Hi all, 2 northern lights and 1 bcn critical seedlings are showing signs what I thought might be thrips, but I haven’t been able to see any bugs yet. I put blue and yellow sticky traps and still haven’t seen any bugs. Any ideas on if it’s worth worrying about and how to fix.ThanxWeek 2

Nutrient burnt leave removal question.Should I remove all the burnt leaves? Worst ones are 25% burnt. Some just speckled throughout.
Do the flowers still need exposure to the sun? Or will the leaves exposed to sunlight keep the buds growing? Can cutting the burnt leaves cause enough stress to hermie or stunt growth?Week 17

Curling serrations along leaf margin, heat related?Could the serrated edge of leaf margin point up slightly due to heat stress? My guess is that this is environmental, I moved light away a few inches just in case. Any other possible causes? Should I be concerned or take any other corrective actions?Week 8
