Question about temps,

[j4s2u0]

Hey guys,I have a question...
Alright I am growing in a pc ect...my problem is the bottom leaves are turning yellow.
I was thinking this was because of nute burn ect but it is still happening even after stopping nutes,
So now I am wondering,can cold temps...like 55-60 degrees at night cause the leaves to yellow?
I know this is to cold at night so I moved the pc off the ground so it might not get so cold...
Any imput would be great,thank!

Also,if it helps...the plants are 22 days old and have been flowering for 12 days or so...
Not sure if that would have anything to do with it or not?
Can leaves turn yellow if there not getting enough nutes?
I am useing re-used soil but dont think this is the issue,but anyways...
Any help would be awesome

These are sympyoms of N deficiency. I know that it sucks but you need to wait. Your plants will not recover from a deficiency overnite. Also how is the growth rate looking? Has growth slowed down? Reusing soil causes a lot of problems deficiencies and pests are the top two. Also when you feed what strength are you using, phed water, water temp???

Thanks for the info eBUD,
The growth right now is awesome,they have defently picked right up...most are another inch taller,and have got another set of leaves already,they only thing I can see is there first to sets of leaves are yellow,so I thought it was nute burn also,but they look great now
And I put the pc on top of a 3 foot high tote and now the night time temps are around 65-70 degres,I figured cuz heat rises it should be warmer off the ground,thanks again man

Hey! Glad to hear they are doing well. Keeping the temp changes to a minimum will maximize growth too. Meaning try to keep a low difference from the day temps to night temps.
Post up some pics so we can enjoy please
