I think there's a formula somewhere for light/sqft of floor. You can get to the point where there's too much light. If you are having to exceed that to get the temps up another light probably isn't the solution.

Conversely, if you are nowhere near the "max light" thingy, having temperature to spare is a great thing for when you can add more light.

If you need a source of heat other than lighting have a look at this unit.View attachment 37121

Is it me or is that thing perfectly named and colored?

I have not used it since i was running blurple in the winter time.lol The wattage on that thing is really low for a space heater.

 

[Punisher84]

Random thought, could c02 be an issue? Such low temps you probably don’t even have an exhaust fan running, if you do you shouldn’t. Not sure how sealed the space is, but could it be an environment issue more than a nute issue?

The garden is still not happy. I have been running an additional 100 watt LED quite a bit the last couple of days. I turned it off for the moment. It has been helping with temperatures, but I am a little worried that I could be hitting it with too much light intensity. I am seeing some increase in chlorosis and some brown crispiness on a few lower fan tips. I let my coco dry out a bit too much as well. I have been trying to bump my tent humidity down a touch from the low to mid 60s on average.

What is your temperature at now?

 

[Chiefer888]

What is your temperature at now?

it was 77-78 with the extra light, 72-73 without

Not sure what you got going on there. If there has been many waterings without the proper runoff you are inviting a lockout to happen. If it were me i would give it a good flush ( 3x the container size) with plane water and a lite feeding.[/QUOTE]

Would you do RO water with a little cal mag (150-200 ppm) or just ph’d tap?

 

[Chiefer888]

My tap is usually 250 ppm, high in cal and mag

I would use the RO water if you have it. Are you watering with that tap? Are you filtering the tap ? One more is your water well or municipal water source?

Municipal water, it smells like chlorine I typically avoid it

Is there any way you can get it higher? Like just south of 90, given your humidity. Or get the humidity down is another option.

I really am focused on getting my humidity down. As the plants start showing sex I am expecting to cull 3-4. I am also thing of covering my media wth something to reduce evaporation. Suggestions?

All kinds of things you can use as mulch. I personally use hydroton clay balls but i do not see anyone else using this method. @Jesselikes2Grow like using small lava rocks. I have seen a bunch of guys use rice hulls for mulch. How high was your lights off of that canopy in the last 24 hs or so? Sorry for all the questions just trying to see what is going on with your plants.

 

[Old ST1R]

A black plastic wrap is also a good method I've seen put to use. Perlite, lava rock, sand, mulch, rice hulls, hay, wood shavings like the kind for hamster bedding, all kinds of good options.

Is any of that REALLY going to affect humidity though? I would think it’s an ambient RH issue that is best addressed with a dehumidifier.

18-19” above canopy

My solution was for helping the grow medium to hold moisture better. Not necessarily for RH issues.
Ventilation or a dehuey is best for RH solutions.

@Jesselikes2Grow can you have a look at these plants and see what you think.

I gotta read into it a bit more and see.
But me thinks so far it's a mg and zinc def for sure, prob something else as well, lights too close and nutes too low do that to mine.
Too much light not enough fuel to use it will cause defs.
Also had the reverse.
Not enough light so too much fuel. Lol.
Was the ph of the coco ever checked?

Not sure about the PH. I could not help but think lights as well. I have seen mine do that same thing when i got the lights to close several times. Also they do appear a bit light in color as well. What is really strange is they looked like they were getting better then Bam droopy again. @Chiefer888 if it were me i would give then a GOOD flush ( at least 3 gallons of RO for the 1 gallon pots ) . Back the lights off to like 25" or so. After flushing follow with a good dose of nutrients. Then monitor and see how they do.
