Live Stoner Chat pH

This little guy is sitting at 7 weeks. I never kept track of seeds and there are auto mazar and a random free auto lemon seed was popped. I think this is the lemon. This plant is the healthiest in appearance with little yellowing tips and little leaf curling. The others can't be moved and it's lights on.

They look fine to me

Run off is what's no longer in the medium. It can give you a rough idea, but if you want the pH of the coco, slurry test. pH and ppm.

From the pics, I don't see an issue, but I slurry every 3 weeks just to check.

Guys I'm concerned about my humidity levels at the moment. Today it reached 65% max and I'm sitting around 55% normally.
I'm looking at buying a dehumidifier and there are cheap ones that remove 300-500ml of water in 24hrs and there are medium priced ones that removes litres of water on 24hrs.

I have no clue will the cheap ones remove enough to bring it down or am I better just going with the more expensive one.

Thank you

What's the problem? I run 70-80% RH in veg and 60-70% in flower. My current canopy is dense and my exhaust fan keeps my RH from spiking unless it has been raining or the general humidity in the home is high but then my temp controller keeps me in range.

Know about VPD?

Vapour pressure deficit, no I didn't but I just did a little reading , thank you. I have good air flow. I still have the nooby fear

Stay in ranges of VPD without large fluctuations and you won't have to worry about mold.

Here's a handy air temp. VPD chart. I keep my tent around ~75F and adjust the RH down(70>50) in small increments as the grow progresses. Good stuff!
Keep up the great work...

in summer I use a room air conditioner to keep the air going in to tents already dehumidified. and a reciprocating 48 inch tower fan blowing from top to bottom of plants. Never had bud rot indoors. knock on wood. I would say the sweet spot for RH is 55%. but 40 to 70 will work fine. m&m relax it's a weed and will almost grow itself. think about tropical strains that do fine with 90% humidity all the time.

Agreed. Plus it is those massive environmental swings that cause mold and pathogens. I try to keep everything within a 10 degree and 10% sweet spot unless my I have environmental swings outside the tent but they don't last long enough to to cause real damage.

These rust spots appeared overnight. Any ideas.

Thank you
