Kind of looks like it could be both light stress and calcium issue.

Asymmetrical baby seedling
Hi everyone, just need an opinion on my poor seedling that looks a bit mutated and stressed, came home today and my timer decided to break and just stay on no matter what you press.. My heater comes on when the lights off and was 28c in there 🙄 should I move the light away?

Starting to fade? Or nutrient deficiency?
One of my plants has several fan leaves that are turning yellow/purple, and I can't tell if it's low on N or starting to fade. The plants are 2 days into week 5 of flower with a 9-10 week flower period, so it seems a little early for it to be turning colors like this.

Will my plants survive?
I am on week 4 of my white cookies and they have stopped growing. Very small and weak looking but still got colour. Having over watered them can they be saved? I transplanted them in dry soil and left them for a few days but no growth is happening.

What’s causing my leafs to curl?
Leafs are curling inward on new growth. It’s not exclusive to the tops. It’s only 2/4 plants. It’s still growing fine as it’s my tallest and biggest plants. I’ve adjusted my light down to 2/10 as my first fix and moved the fans around. Any suggestions?

Fan leaf deficiencies during flower. To cut or not to cut?
Day 85 Update: G13 has a ton of fan leaves turning fast. Pretty sure it's a PH issue. Should I wait until they're dead to trim them off or get rid of every fan leaf that is affected more than 50 percent of the leaf?

Leaves dying week 6 flower
Hey growers, I'm at the week 6 of flower, and leaves are dying in some specific spots. Runoff ph was checked, 6.4. Feeding 4ml/L bb top-max & bloom. Bio-Grow was cut off after dark leaves, clawing & burned tips. Does someone know the cause? And how big a deal is it? Thanks!

Unhappy seedling
See the photo of one of my seedlings that appears quite unhappy. My guess is light/heat stress, BUT I have 8 other seedlings growing right next to it, under the same grow light, in the same soil, that are doing just fine. See 2nd photo of another of the same strain that's fine.

What can be the causing of the leaf curl upwards beside the obvious? like heatstress, waterdrops or maybe roots? seems also unlikely to me she has the same feedings as the strawberry. my other plants are fine. more info in the text. Thanks in advance
