twisting leaves-pix/info

Ok, I have been trying to figure out what the issue is with these plants, they are about a month in, and not all of them are like this though. The leaves are starting to twist on some and on another the tips are curling under(2nd pic), and on last one it has a few brown spots in addition to the twisting...

White satin, Kalichakra and Safari mix
****
1k MH veg/1k HPS flower
Foxfarm ocean forrest soil with FF tri pack (about 1 tsp per 3 gal)
Molasses, a nice big glob..
Run off is a tad high at 7.1-7.2 ish
Tap water comes out around 8.2ish (adjusted down to about 7)
Watering every 3 days aprox
Humidity at 31, at night can drop to mid-upper 20's
Day temps range 73-77F,
Night can get a tad nipply around 61F.

But yes, I did look this stuff up with not much luck..
Any ideas would rock! :jointsmile:

I'd measure your molasses instead of using "one big gob"
Get your ph straightened out (both water and soil runoff should be 6.2-6.8) instead of "about 7.1, 7.2.-ish"
Get your night temps up

Well it's with a tsp so it is kind of being measured. Globs work for everyone.
A couple are around 7 but the highest was 7.2. Figured it wasn't high enough to make a big deal to lower it right right away. Could wait an extra day until watering time then do a mini flush and lower it that way.
I just haven't seen these issues with that small of a pH diff. So I thought I would check other options before.
Night temps are unfortunately as is...no idea how to warm it up. At least it's not drastically cold...they should still do ok.

Right, that's kind of why I had questions about a glob.....I put a glob of molasses in my hydro system once and fried my plants pretty royally so the glob working for everyone.....

Poor drainage can lead to ph problems where ordinarily the plant could take it....hows the drainage for that plant?

I think the cold night temps can also be adding to your issues but I'd love opinions from others about that. Is the plant on the floor?

yeah I wasn't too specific initially was I, my bad but just about as much as you can keep on a tsp from the jar to the bucket. Yours fried once? first time hearing that with molasses. I personally have never used it but after seeing so much good with it why not?
so maybe that is the issue...
But yeah the fact it's only like 3 out of 8 is weird (yea, 8 girls out of 10) as far as drainage it's good. Every watering it filters through the bottom so drainage isn't an issue. There's like at least 20, 1/4'' holes under each with about a good 1/4 to 1/2'' of perlite layer on the bottom before the soil, but the pots sit on carpet.

Well I'm not a soil pro but if those were in my hydro setup I'd call it overnute and/or ph but overnute would be my first guess.

The normal dose for molasses is 1tablespoon per gallon......do you recall how much you added per gallon or quart or whatever?

yea about tsp per 3 gals actually, sometimes 2 tsp per 3 gal so neither are too much. and with the fert's it's a tsp per 3 gals's, so thats weak too...except for the big bloom, it's been 5 tsp per 3 gal as of lately, but this was like this prior to the upping...
pH for now ide say

Honestly I think you might have a touch of both. Good luck. ;)

yea prolly so, thanks man I'll see what happens :thumbsup:
