either too high temperature or too much light. Try raising your grow lights or dimming them!

Leaf tips curling on top
What’s causing the leaf tips to curl? I moved the light away and reduced the power to 75%. Please advise on how I can address this. Looks like her growth has changed, a bit slower and a bit lengthy.

Weird Leaf Problem
New leaves show strange twisting/curling. Humidity ~50%, temps 28-21°C (D-N). Did LST last week—could twisting be due to reorienting to light? Using All-Mix soil, Bio Grow, Calmag. Water left 24h, not pH'd. Some leaf holes caused by me. Flipping soon—help resolve this issue!

What's causing my brown crispy leaves!?
Over the past week my plants have taken a turn for the worse. Many leaves went from yellowing to browning to completely crispy! Other leaves have brown spots on them and some of the stems are purple.

The leaves have become glossy and yellow
The last couple of days, the leaves have lifted a bit again and bent the edges, and the leaves are glossy, was it a mistake to keep the light on 24h the first week, or what do the last couple of pics look like? (I have now set the mode to 18/6) so as not to fry the plant

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.

Why are the sides curling up? Question not about them pointing down but only about the sides curling up and very small brown points
What is this? Sides r curling up. Day temp didn't get over 23 degrees night temp is +- 12 so I don't think she got too hot. Points bit yellow Saw this yesterday evening too, today at 1 plant a little bit. They're probably pointing down because of the low night temp so that's ok
