First grow with AC Infinity 4x4 tent

[rats]

Plants are still looking good! The leaf curling appears to be isolated to the first leaves.

This is day 13 and I just watered with a mild nutrient solution and plan on transplanting to bigger pots within the next week.

Oh man life got away from me for a few days but I finally got some time to transplant. It is day 16 from sprout I have ffof mixed with about 30% coco and 5-10% added worm castings for the bottom 2/3 or so and then happy frog with the same ammendments for the top. Watered with calmag, seaweed, compost tea and ph'd. Moved the light up from 18" to 24" to give them a break for a few days.

I use RO water and my meter shows it's EC is .008 Ms/cm / 4ppm after these mix ins my waters still only 162 ppm is that too low? I don't want to strip nutrients from the plant/soil.

Other than that I feel like things are going well and my plants are happy. Keeping the tent about 78° and 72% RH. Planning on topping and starting my LST once they recover and the get another node or 2.

Always open to suggestions or advice from more experienced growers

I could also use some suggestions on how to keep humidity up. My lung room got down to 28% today and I went through almost 15 liters of water in 24 hours. I was venting inside at first and that helped a ton but I can't keep my lung room at 60+% so now it vents outside

Not sure what your home HVAC system is but mine has a base setting of off and 25-45% humidity. When I need humidity like seedling and veg I set it at off and let it float up to within 10% of my average humidity need.
Much easier to add humidity in a tent than in a room in a house for sure.

Ive found temps and humidity a continuous fight. If your tent is 70 something rh just vent your tents exhaust into the room and keep the room sealed off best as possible.

What Im in the middle of putting together. I figure my tents will be exhausting humid air either from a humidifier in early stages or from the plants in later stages. Portable ac and dehu in the lung room targeting low 70s and 45%. A humidifier and heat source for each tent. I would like to also be able to use the closet in my lung room for drying at 60/60 when its time. My only concern is opening the tents for maintenance with the room that cold.

I'm growing in a detached shop, the only climate control is a window AC and a portable heater unfortunately.

Will above 60% RH inside not cause issues? Googles saying that's too high and can cause mold and mildew issues. I'm sure once the plants are bigger managing humidity will get easier since my airs too dry.

I have my fingers crossed the window AC unit can get temps down for drying come summertime. There is a small closet I could seal off and duct into.

Thanks!

Edit: honestly now that they're in bigger pots and the wet soil has more surface area it may help with RH I'll keep an eye on it

Good airflow in the lung room. Going in and out of the area will exchange air.

I am in Arizona too. I was at 30 or so rh and now that the ac is off , the plants have grown they are at 50- high sixties. In flower you will see a spike in humidity after lights out. I keep my tent open for temp reasons in the day and open it after lights on. I have the exhaust on almost full blast and the intake behind. That’s during flower. The desired temperature is probably impossible for me to accomplish let alone afford. Your plants are off to a good start. Why did you mix soil with coco and what is the reasoning for using r.o water?

 

[JIMKSI64]

Going to need to drop humidity later in flower. 55% is the warning level and below 50% is better.
Depending on area/volume of the shop a 50 pint per day may be needed.
As a test run the AC and the heat and see if the AC will dry it out as the heater keeps it to temp.
AC recirculates your air and does not draw from outside but may pull water out.
Below 30 freezing up on the unit may happen.

I don’t have gas. Out here we have heat pumps/ hvac. So my unit also operates as heat and as you said will lock up around 30 degrees leaving you without heat. These are the same units being forcefully installed by regulations in areas where they always are reaching temperatures lower than 30 degrees in the winter.

I'm having the opposite problem I'm struggling to keep my tent/shop warm enough but I have a higher wattage heater on the way but I think I'll be able to manage higher temps once it starts warming up.
I've used coco for other soil mixes and my non cannabis plants seem to do well and I thought I found a good amount of info saying it's worthwhile but now I can't so I'm not sure it's a little late now I think. I have a RO tap that I use for drinking and watering my other plants, My tap water had a pH around 7.9 and ppm near 500 would I be better off starting with that?

500 ppm tap water begs for a water test. If you can get the municipal test results that are free either online or call the water company.
500 is a lot.
Parts of this country have different versions of calcium. Some will not be useful in an organic grow but should be counted if used in a salt hydro grow.
Ro water was recommended by the test company I sent my samples to.

Samples from 2022 are showing 190-970ppm, so I'm near the middle. How do I find out if my calcium is useful?

 

[rats]

Im also wondering what could be going on with my plants older leaves, it was isolated to the first true leaves but it seems to be working its way up into the next set. It looks like a calcium deficiency from what I've seen but I'm adding cal mag to every watering to supplement since I'm using RO water and pHing the water to around 6.5.
Do I need more calmag or could it be something else

 

[rats]

1 and 4 seem to be doing good, 2 seems to be getting better the leaves have perked up quite a bit and no new spots for a couple days. 3 is obviously doing the worst I see new spots every day. It seems like it's eating itself from the bottom up but new growth looks healthy too me.
I haven't watered the plants since the 2nd when I transplanted them and the pots are still heavy and damp about 3/4 inch down

No leaves are touching the soil and the yellow sticky traps were just to keep leaves off the soil while they turned up towards the light.
