The leaves are starting to turn brown on the edges. Not sure if it is heat stress or neut burn. Figured I'd try to nip this one in the butt this time.
Young plants turning brown, starting to curl.

thanks for the reply! Not sure if i waited too long to transplant? I decided to give it more time this grow to maybe have a nicer root ball to stress it out less. Giving them 20 ml canna coco neuts for 2.5 gal with 2.5 mlcalmag and 2.5ml rapid start. I started with 10ml and then gradually went up to 20ml canna. Plants are 4 weeks old. room has been a steady 80 degrees and the fluorescent is about 2-3 feet away. I'm growing it the same way using the same amount of neuts as the last grow which was the same kind (AK4
. The only thing different is that i redid the room because it was old and grungy, and that i waited a bit longer to transplant.

What nutrients and growing medium are you using?
lol, asked and answered, noone reads!
The first and the 3rd pic seems to show potassium possibly lacking, or was lacking at one point, the 2nd pic seems to be either a magnesium issue, or possibly the big leaf above it is blocking the weaker fluorescent light above it and the plant is letting it go. Growing in coco, while i haven't done it, know that coco, if not properly prepared, can contain alot of sodium, which competes with potassium and magnesium for uptake. The 4th pic though, shows the plants overall look healthy, and new growth and even just below that node, looks great. The burning isn't very consistent, it's not uniform to the edges of both sides, i wouldn't worry about it. Im assuming you're ph'ing when watering?
