Need help! Leaf tips curling down.

[Truu]

Last night I watered my plants because some of the leaves were beggining to droop. Gave them 1.5 tsp tiger bloom and .5 tsp big bloom. PH was right, watered with 1 gal. Not showing any signs of being burnt. I dont think it could be over watering because I have very good drainage. I dont think it could be under watering because I just watered with 1 gal and had plenty of run off.

I'm using cloth pots, 5 gal. Has anyone had any trouble with water draining out the sides? It looks like the water is draining good, but after sticking my finger in the soil I noticed it is moist, just not as moist as I expected. Seems like the top of the soil dries pretty quick in these pots.

Notice the color is starting to fade away from the leaves? Its just on this one plant, and it wasnt like this ~11 hours ago. Never had this happen before.

My first guess would be over-watering. But that would probably be too easy.

Man I just dunno noods. Like I said I gave them a gal with plenty of run off. I'm afraid it might be underwatering. But then That one plant has leaves that are losing color. Ughhhh hate when shit just doesn't go right when You bust ass to do things the right way!

I was thinking, could these symptoms be caused by the soil getting cold, or my water being to cold? We did have a nice cold front come through.

I'm going to have to agree with Noods.
Looks like over-watering. But it should perk back up in a few hours

Truu - I understand your concern--I have had a lot worse for sure and your plants look healthy as they should. And I am in no position to make any off the cuff experienced judgement concerning deficiencies without consulting one of my grow books or online research. However, take a photo outside the grow room for better clarity. Looks like lights are on or mylar is hindering details. Let these pros know what your RH is or was after watering (mercy don't forget the ph never ever forget the ph). Speculating that after watering with lights ablaze it raised humidity and could be the upper leaves rapidly absorbed the feeding including the surrounding humidity--particularly if air was not circulating well or temp. was up. The stalk looks like it has been retaining a good deal of water (green fresh color). Like some of the old timers have stated the autos are accustomed to harsh conditions including droughts. The above commenters are probably right on point with the exception of addressing the one leaf. Lastly, if it doesn't clear in 24 hours, take a photo of the single leaf--post and someone will come to the rescue.

Cool thanks Alan. The circulation is def up to par and then some. If they aren't looking any better later tonight I will put a picture up with them out of the tent. Thanks for thehelp buddy.

Sounds good Truu. Your a popular guy--almost more "liked" than "posts" may be an award or form of recognition for that herein. cg

pH will be affected by low temps... usually drops. I had a problem recently because I just changed grow areas and the new one is exposed to the elements, to some degree. Before I got my temps regulated, I had a problem with pH because of it. You'll need to check your soil pH first and go from there. If the pH is off, everything is off.

Alright guys my onyx is going downhill here. No idea What's causing this. None of my other plants are having this problem and they were all fed EXACTLY the same. Any ideas?
