Yellow leaves w/some weird spiraling.

[Hotblondz13]

Hello there , need a little help with these plants. They popped out of the soil on Jan 28th , been doing great since about 2 days ago. Not sure what’s going on these things. A few of the top fan leaves have yellowed and the some of the new growth seems to be growing in a weird spiral pattern. I thought the light may have been too close , I raised it up a couple of days ago until the PPFD meter was showing 505. I just got the meter a few days ago so I’m not sure what my levels at the canopy were before that. Could this be an underwatering issue? The pots were super dry before i watered them yesterday (showing 16% on the Mars Hydro moisture meter). Any help would be appreciated. Here’s some more info :

3 Mimosa Evo Strain ( Barney’s Farm)
1 LSD ( Barney’s Farm)

2.7 x 2.7 grow tent
Mars Hydro TS-10000
4 inch exhaust fan
Oscillating fan
Exhale co2 bag
Temp: 72-79 degrees
Humidity : 55-65%

Plants looks great. I'm having trouble seeing what you describe in the pictures. I say keep calm and carry on!

On the 2nd picture i see a small damage. Could look like it got pinched a bit but it was a bit hard to spot

Spiraling leaves could be whorled phyllotaxy. It's harmless. Some yellowing can occur after watering, which is also not a problem.

I see 4 plants, i believe , 2 about same height, 1 small and 1 tall .

Just my 2 cents, you might have a slight challenge for you lighting on the smaller plant if you have a 500 ppfd on the tallest plant.

I would top the tallest plant even with the second tallest plant and put the smaller plant on something to bring it up to canopy height.

Other than that your plants are beautiful

I looked again at your tallest plant, looks like u have already top it once ?

I see nothing to be concerned about. The plant is just growing very quickly, the leaves will straighten out.

Back corner leaf looks fucked but overall good nothing to worry

Tips are yellow soo there is lots of food your good.

Thank you so much for the info. The plants seemed to have resolved their twisting growth pattern with a full watering and some light readjustment. I also raised up the smaller one to match the rest of the canopy. Yes , I did top the tallest one in the tent. I was a little apprehensive to do all of them due to space constraints. My only issue now is getting my humidity in check, it’s hanging around 70-78 , even with the exhaust fan cranking.

cover the dirt like eartboxes do it will reduce evaporation from the soil at least. plant transpiration is only with airconditioning or dehumidifier removed since your fan cant handle it

Yes a dehumidifier will be ur best friend, if u don't have one get one thats u can control.
I half to mcguyver my ac.

Are the walls of your tent are sucked in really hard from the fan pulling? If so it's probably struggling to remove enough humid air, especially if you use a carbon filter. Make sure your doing everything you can to maximize the rate at which the fan replaces the air in the tent. I've been using an intake fan as well as exhaust and find it very helpful.

I definitely need a dehumidifier before I go into flower. I know AC, Spider , Mars, and Vivosun make some nice units. , but I'm not necessarily wanting to take out a second mortgage to buy one of those unless i absolutely have to. If you have any code effective dehumidifier suggestions please let me know. Here’s a screenshot of my control panel as well.

Amazon has some controllable dehumidifiers for under $200

I have a non controllable AC to macgyver for flowering.

You do want to have dehumidifier in the lung room, u should calculate the sq. footage in lung room for dehumidifier pick.

My ac is way to big for my lung room, but I figured out how to make it work, im growing old school.

Rock on, keep on growing!
