Drooping plants

My plants have started drooping, it has gotten cold the past couple of days, down into the 40s. They’re in my garage under four 4ft T5 light fixture. They are in a good soil with good dranege and has the appropriate amount of nutrients and the PH levels are good. They are near a small heater and a fan(I put the heater near the plants on low after the first cold night when the drooping had started). Could it possibly be from over watering? I only water them when the soil is totally dry.

if your growing in a garage with a concrete floor you need to raise the pots off the floor a couple of inches as the cold floor is cooling your roots, try to aim for 18/19 degrees for the root zone

Looks like a calcium deficiency

New growth really light green, red stems

Or overwatering, you'll know it's calcium if little brown spots start appearing

Can you enclose them in some way and heat them ? ..and bob said get them off the floor & that's the first thing I'd do too buddy.
-good luck

The leaves drooping in that manner is from over-watering, not just how they hang, but the 'puffiness' on the leaves is from watering too often. As for any possible deficiencies, more info would be needed, though it does appear off hand that they're suffering from a lack of magnesium.

my area of expertise here with doing it in the cold. fr one with the lights youre running as well as the cold your plants arent going to uptake like a normal plant. so what you need to do is raise em off the floor if they arent already, do light feedings, and do not water to run off. youll want to not water as often either until the temps go up. the ph of your soil will change as well with the cold temps and cause red stems

Your plants are cold bud. Thats it do as suggested above.

Bwahahahahha bright green new growth and purple stems is your calcium deficiency? Here is a tip for you so you arnt mis diagnosing peoples babies.
Nutrient deficiencies can be either "mobile or imoble" Calcium is a mobile nutrient which means the lowest foilage is effected first as the plant draws calcium from the lower leaves to fuel new growth. Step 1 in disguising deficiencies is finding if the deficiency is moble or not.

Calcium is immobile<<<< not mobile or "imobile" as you wrote. Check your facts before looking like a fucktard.... fucktard

Calcium is a semi-mobile nutrient, so the signs of a calcium deficiency begin with the new growths on your plant, but they will start moving after a short period of time.

Yeah I'll stick to what I've learned from an accredited University, MSU, that states Calcium is in fact immobile, over info in a blog. Sorry you had been misinformed and thought you were giving good information.

Even indoors I lift my pots, even if it is only on two pieces of 1x1.
It thermally insulates as well as helping the pots drain freely.

If you have a link i would be happy to read it but because of your post im looking for more information but site after site including breaders are all saying semi moble.

Ditto I keep my trays of cuttings and or seedlings up on big plastic crates and if I have a spare propagation mat I'll put it under the crate so that heat can rise up and warm them when needed..

.. when temps are in the 50s they're not going to grow (or growth may be so slow you won't notice it), in the forties they're not going to survive long

I suspect what he's got going on is he's over feeding and watering because he's treating them as normal plants instead of plants that are basically in shock from the low temperatures, they're not going to use nutrients or water so it's going to build up quickly, jmo.

I think he may have you on this one. I believe it is immobile in the plant and semi mobile in the soil. No worries though, you are more helpful all around than he is.
Use EDU sites, try googling this: calcium immobile "edu"

I've notice you are all over the place giving 50% good advice and 50% bad advice because you do not know the plant. I knew you were headed for a battle and I see you fight back so it should be fun to watch in the future.
College taught you a lot but maybe you should learn about growing cannabis before trying to help people. Far to many of your posts are wrong and it is only a matter of time before people are going to start attacking your advice.
Hope this doesn't cause butt hurt because I was much nicer than what you are in for.
My advice would be to go back to asking for advice not giving it.
Happy Growing!

Wow..now that's some bad advice!!! lol.. yes nutrients are mobile or immobile lol...calcium is not a mobile nutrient..it is immobile and deficiencies start at the top of the plant!!! Before you bark at others...check your facts, you seem to no less than the person you replied to! lol

As long as the plant transpires, calcium will be moved in with the water.
If you are having a cold spell or live in a humid area, you may want to look into mixing calcium chelate to drastically increase the uptake.
