Looks to me exactly like the hear stress I saw in my outdoor lady last year.. 30 or higher is just too hot with them.. Especially if the humidity gets lower. A fellow grower Mrs_larimar turned on to this Chart.. http://www.just4growers.com/media/23631/vpd_2degree.gif .. lovely visual representation of what the plants need are.

If you have issues reading the chart... It basically says optimum Humidity of 60-52.5 rh is ideal for healthy vegetation in late flower with a Temperature range of 30 degrees Celsius. Try to move it to a more shaded area that still gets an average amount of sun.. Again it's a wonderful chart and I hope this helps.

Strange leaf deformationHave these strange leaf formation on some of her blades, looks liker the main vein has somehow outgrow/stretch, with no actual green stuff around lol. Several leaves have this. Combined with a slightly general canoeing, could it be from a nitrogen tox ? Growing good though
Cheers

Update on previous deficiency questionUpdate on previous deficiency question
The leaves got worse, its still only a few so not too bad. After doing some research i think it could be a Manganese, magnesium and/or Sulphur shortage.

What’s wrong with seedling?What’s wrong with her? Tangerine dream auto sown directly in FFOF on June 8. Growing beautifully like a weed (lol) but color is weird, looks patchy and mottled. Did from the beginning hope she’d outgrow it but no. Under a fairly mild 45w led. Thoughts?Leaves. Edges burnt

Cal/mag problem or heat issue?A few leaves have some problem spots popping up here in week 6 (see pics). No nutes, PH’d water. FFOF/HF/Perlite mix for medium under 20 hours of light. I’m guessing either got too hot from being in 90F heat for an hour or needs cal/mag? Any advice from any veterans out there?

Leaf burnt edgesOne leaf has burnt edges and is a little different looking, than the other leaves. Is this some kind of nutrient burn? I am using a light mix soil, and have not fed the plant with additional nutrients, except for a little root stimulant (half of recommenced dosage).

Dying leavesI had some mild nute burn last week on a few plants. A few tips were burnt. Some lower leaves are turning yellow and dying. Is this still nute burn or something else?
