Plants are curling and turning brown from the tips inward need HELP!!!!

this is my second month and they were doing great looked very healthy, but about a week ago my leaves started turning brown only at the tip. I didn't think much of it. and a few days later BAM! there curling up into them self's and turning brown and there looking crispy. this is my second grow, m first one was outside and she turned out beautiful, so I thought to try it indoors. I am using organic starter mix, with a 6500k bulb at 85W. the light is almost 2 inches from my baby. I don't know much about the lighting or the soil other than that. I don't know what could be the cause of this iv read multiple things giving me different causes I just need good advise from someone that's had this problem before. thanks to anyone who can shed some light on this. putting pics up soon.

Cant tell ya till there's pics. No one can. All they could do is guess .. .. .. and you know what happens when peeps start ASSUMING

Looks like she's extra warm.

they look like they been put into an oven, . that's my official diagnosis.

thanks for the advise people, my grow rooms temp is between 72 to 80. never above 80 tho, is that to warm?

80 degrees in the room often equates to an excessive canopy temperature. Definitely looks baked to me.

you shoudltn have more than 1 plant per pot ^^. really dont share pot. sepparate them right away if possible

Oh and the leaf thing is probably heat stress or magnesium deficiany .

Good luck
!

Take care of them, or they might get up and run away they are dying

I think it might be to late to separate one of theme, the roots are intertwined together and i am afraid if I try to repot it will kill one of them. is there a safe way to do that with out harming them? I really appreciate the REAL comments from my fellow stoners.

get one of those indoor outdoor thermometers with the sensor on the end of a long wire. Hang that thing at the growing tip. See what the temps are. You're light may be too close and is burning up those poor leaf tips.

I doubt its anything but being too hot. Sort that out with additional cooling. Can you describe / pictures of the grow room?

iv got my temp down to a cool 72, im using an infrared thermometer and temps on the top leafs read 75.5, my fan is rotating maybe a foot an a half away from my plants. my grow room is 10 ft x 10 ft. my light is 6500k 85w maybe 5'' from my baby's puts out little to no heat. Im running her at 18/6 day to night. iv done a lot of reading and at first I thought it was a nitro def, but from the pics iv seen I couldn't tell and didn't want to assume.

even if the roots interwine you can still sepparate them. if done carefully it wont shock the plants much. Also its important cause if roots interveine they stund each others growth anyways so.. and even if both cant be saved you would be better of with just removing the smaller plant.

Basicly u can pull a plants roots up with brute force and replant it and it will still live, even if it will be VERY stressed, so you shouldnt worry about killing the plant by repoting.

can you please explain in detail the steps of the leaf development up to the part where its only dry brownish? this would help to make a correct evaluation of the problem.

the edges started looking a brownish/yellow color on the tips of the middle leaf. the next day the tips started to curl upwards and were dried out looking. I have another that started the same way but started on the bottom leaves. If its the heat wouldn't it start from the top?

grow room is an 8x8 office in the back of our house. one door leading outside opened occasionally to let in extra light. one window which is blocked off from all external light. door leading out into house is covered. use an inexpensive set up. a indoor/outdoor temperature gauge , temp stays between 72-76 deg during light. 67-68 at no light. med size fan to move around the air. im using a 60/40 water mix..60% tap water 40% ro water...doing this with a supportive but displeased wife so I cant spend much money on it.
