Seedling Issue. Low Night Temps?

[KaptainKush]

On my second grow and i didnt run into this issue on my first round but i am growing in a different room and temps are dropping outside so i was wondering of that was caused the issue I'm ran into. I have already fixed the issue but i want a second opinion just in case i should be looking for a different culprit. No nutes used. Water ph at 6.4.

What's the temps in there? Floor can be cold enough to slow absorption. I.e. Slow growth.

Rh 40% RT 72* was getting as low as 52* with lights off before i fixed the temps. Now its gets about 65*

Feeding with what?

 

[Smerb]

52 degrees is cold.

I havent given them any nutrients as of yet.

Ok, they are just looking for a bit of food. Next watering they should have a feeding of nutes. You'll see them green right up.

 

[KaptainKush]

I'll do just that. Appreciate it man.

 

[KaptainKush]

What ppm should i be shooting for with such small plants?

 

[Smerb]

400 ppm or below. I don't check ppm anymore. Seems the same always.

 

[KaptainKush]

Got it. Thanks again.

 

[Smerb]

Got it. Thanks again.

Keep updating here man.

 

[Smerb]

I'd like to see them green up.

What did you do to fix the issue?

Space heater when lights go out

Yeah 52 is pretty burrr, your RTZ is probably a couple degrees cooler.
Cheers and happy growing

Found that my babies were a root bound. Checked the bottom of their cups and the roots were pouring out of them.. So I transferred them into 1.7 gal pots filled with Happy Frog. Hopefully that'll help with my issues.

My advice for temps is firztly get tube heaters wirh thermostats to warm grow area. Second use warming cables for Vivarium wrapped around pots to keep the soil warm and lastly when watering and feeding make sure water is an not cold!

Oh and next time use fabric pots to stop rootbind.
