HELP ME!!!!
this is my first time growing I’m still learning and trying to pin point the signs and stuff but I don’t know what this is. It started to show and spread about a week ago and It’s only showing on these two leafs. I don’t know if the soil ph is off or if my fan is blowing to hard or if my plant has some type disease. I need help any suggestions?

Hi there. I'm old but only have one completed grow. Have you looked at the GWE main site's leaf problem identifier? Could you post a pic of more of your plant? Do you pH the water? It doesn't look like wind burn. Are you growing in coco coir or? Giving nutes? What strain, how old is the plant, and what size pots? Hopefully a more experienced grower will chime in, more info helps. Good luck!
 
What strain, and auto or photo? Usually at that age watering isn't needed that often, let the pots feel lighter in weight before watering again. You really don't want a lot of runoff, you're letting your nutes go down the drain. Did you use perlite in your coco coir? The medium could be too compacted. Hopefully someone more experienced can help with that. Pictures help. The drooping then the morning change in looks aren't uncommon. Good luck!
 
Thanks a lot! I'll keep that in mind. The strain is auto.

The pot actually feels a lot lighter after two days without water. And the top layer turns almost crisp and yellow. Yes, I used perlite. Now I'm thinking I've messed up the proportion the guide suggested. I mixed a 650g coco brick making 10 liters of coir (2.6 gallons) with half a 2 liter bag of perlite (2 quarts or so but the guide suggested half an 8 quart bag).

I'm sorry for the lack of pictures. I'm too paranoid to post them due to legal reasons (or, say, illegal).

Often it's 30% perlite, and perlite in the bottom of the pot can help with drainage. Are your temps and RH staying in desirable range, regarding the top being so dry? Or your light height too close. An auto is a good one to start with. You can put extra perlite on top of the coco coir.
 
Ah, shoot. The proportion is messed up then. I'll put some on top right away. Thanks! It's been a very hot week where I live and the temp exceeded the desirable limits. It's nearing 90F (32C) in the grow tent. RH is 51%. I fixed the lights as high as was possible: 30 inches (77 cm) from the top of the plant and 42 inches (107 cm) from the pot.
 
Fighting the heat here too. Since they're autos I can leave my closet doors partly open, I have a tower fan blowing the house's AC air into it and a ceiling exhaust for heat escape, no tent. I'm freezing two empty Powerade bottles with water to place inside there, or in front of a fan. Not sure how your lights are configured but with LEDs the heat is usually felt on the bottom, a fan blowing underneath them might help to disperse the heat. It's a battle. Post after your next watering about runoff and I'll try to tag someone who might be able to advise you on that. Good luck!
 
Thanks for the advice! Now to the current update. I watered my plant yesterday with plain pHed water (1 liter or 0.2 gallon) and waited until the grow lights went off. Still no runoff but the plant drooped just slightly, not as scary as the last time with 2 liters (0.5 gallons). Other than that, it looks pretty happy. I think I might have noticed some pistils (the plant is nearing the end of its 5th week). Today, the pot feels very light again. Should I maybe water the plant more often, every 24 hours instead of 48 hours?
 
Do you get Nebula's weekly email on Sundays? Part of yesterday's explained watering habits in detail. The 5th week is normal for flowering to start with autos. The tent's temps might be drying the pots out sooner right now. Do you use saucers when watering, to check for runoff? Does water come out the sides of your fabric pots/do the sides get fully wet? My bottoms will feel heavy when the top halves of the pots are totally dry. I get bottom runoff if I want it, if I want to check the pH.
 
No. Could you please give me the link?
Yes, I use a tray on a slanted surface. No, the water reaches the bottom of the pot making it feel and look wet while the sides remain dry.
 
Hey! Yes, all your advice was very helpful, thank you. I guess I managed to caught the rhythm of watering. My plant seems to like 1 liter with nutes and 1.5 liter plain water. Despite of the lack of runoff, it looks happy and is stretching pretty good. I think it started blooming.
 
Week 5 of flowering, unsure of the strain
2x4x5 tent with a 315w lec light.
I haven't fed anything since flowering except a little calmag due to being planted in a supersoil.
checked today and not sure what the weird browning of the bud is, the rh is in the 30-40s range and the Temps sit around 82F
also attached some photos of a healthy bud from the same plant.

Oof. I would think light/heat but I don't know your lights. I'm fighting to stay 80F/40% on the non-watering days so you wouldn't think mold. Hopefully some will weigh in later. GL!
