New Grower, Need Help

So I stated my grow about a week ago.
I have planted
2 ak47
3 white widow
2 white lsd
2 great white shark

They are set up in a 4x4 grow tent, inside of my closet. It has a 4inch carbon filtered ventilation system pushing air out through a hole I cut in the closet wall.

I have 1 clip fan inside pushing air around.
A both a dehumidifier and humidifier (though not very efficient)

I also have one larger fan outside the grow tent but inside of the closet to push air around..

Ok so my grow was going fine until the 1st night I turned off the lights that morning I came to see humidity as high as 99% and mold on the soil.

I did what I could to remove the infected soil and sprayed the plants with a mix of vinegar and water to disinfect them.

I did not prun the leaves as they are new and I didn't want to cut the only leaves they have right now..

Since then I ran into temp and humidity issues for about 3 days where my Temps where as high as 85 and humidity was upper 60-70%

I think the heat stressed out the plants and caused them to need more water because I ended up underwatering them I was very cautious because of the mold.

I have since fixed the underwatering issue and they seem to be making a full recovery but then I ran into WPM issue (I think) so I wiped them down and sprayed them with a mix of hydrogen peroxide.

That was last night and I just did it again this morning.

I turn the lights off every day at 11am and on at 7pm.

I was watering everyday but now I'm just paying attention to the soil and their needs as I space out their watering.

So my problem is some of the leaves that weren't damaged from being underwatered are turning yellow, on one plant brown as well as white spots on some leaves very few but I just want to treat and catch early.

I realized I bit off much more than I could chew on this grow being my 1st official grow but hey here i am im trying to do my best yo be successful. Please help.

I hope that's enough info.

I also have videos but they are to larger to upload but I can send them to anyone willing to help..

How are you getting air in and what is causing the heat?

First I would have the filtered air exhaust into the room so fresh air is drawn into the closet. Check the ph of your soil, the vinegar may have made it too acidic causing nutrient imbalances. I wouldn’t use that brand soil again. The soil must have been loaded with spores. You may need a dehumidifier in the closet too.

you shouldnt spray anything directly on to the leaves, this magnifies the strength of the light hitting the plants. all feed/water directly into the soil

Having a humidifier and dehumidifier is pointless. It's just going cancel each other out. And if there that young you dont need to be spraying them with anything it's just going to stress them out. Sounds like you need a more powerful extractor and a inline fan for proper airflow.
And also with it being your 1st official go of it I'd just stick with one for now and get the feel of things

Thats a strange amount of time. 18 hours on is recommended. Dehumidifiers put off a lot of heat. You likely dont need to be running humidifier or dehumidifier right now.

Thanks for replies guys... I don't run them at the same time. I was running the humidifier when they were 1st planes because I read seedlings need about 70% and they said to lower about 5% ever day I believe. I only run the dehumidifier at night because the lack of heat from the lights increased the humidity. I haven't sprayed them with anything else. And I will shorten the darkness time by
2 hrs.



Also I

So Your saying move the vent to the closet? Instead of inside of the tent?

Im getting air from the closet door being open cause its air conditioned. Then there's a fan inside of the closet to push it around, I have shoots open in the grow tent to allow air in

Heat is from the lights

Every 90 deg turn in ducting greatly reduces the cfms going through-you want to keep the ducting as straight as possible for maximum air flow.

Yeah thats a real mess. Connect fan to filter using a rubber coupling. https://www.amazon.com/Fernco-P1056...eywords=rubber+coupling&qid=1605387464&sr=8-5

You'll be much more efficient if you'll remove 80% of the flex hose between fan and filter. Straight line whenever possible. Good luck.

I’m aeying vent the hot air out of the tent into your main room and draw fresh air from the main room into the tent. With the tent in the closet you have a lot of hot air being circulated around and not much fresh cooler air coming in.

I second this, as it allows the room to become the buffer zone, for all that hot air being extracted, to cool down before circulating around again into the tent.

Thanks guys for all replies. Plants are doing much better. I set things up to pull in fresh air. I see kind of craters in the plants leaves now.. like cracks at first I thought it might be peat but no sign of them at all.. my humidity has been a bit low lately. Could that cause cracking in the plants leaves?
