Ventilation system; Yes, 4’x4’x80” tent. With a 6 inch inline fan for exhaust and another 6 inch inline fan for the light hood, and three small fans around the tent.
AC, Humidifier- YES 2 humidifiers
Co2; No
She’s in the second week into veg. I noticed a little yellow tint in the leaves, wondering if it something to worry about?
Thanks,

Thank you!
The first pic was outside the tent and the second pic was inside the tent.
I have two humidifiers and it doesn’t increase the RH at all, all numbers are from runoff and I have been using distilled water up until I started using FF Big Grow. I mixed half gallon of tap water and half gallon of distilled water. It looks the same since the feeding was yesterday, early.
TIA,

Welcome to ILGM! Looks pretty good to me. Good setup, too! The yellow might be the start of a magnesium deficiency. You’ll probably need to add a cal/mag supplement with distilled water. Take the humidifiers out of the tent and put them in the room near the tent. Your exhaust is sucking all that humidity right out, and your filter is soaking it up, if you’re using one. In the room, it’ll humidify the whole room, and the exhaust will pull it right in the tent. Also, slow your exhaust down as much as you can, and maybe even restrict the intake some. That will slow the velocity of the air, which should help with humidity, too. Runoff PPM is okay, maybe a little high for that age, but not ridiculous…you can see the tips just starting to yellow from that. When it’s time to water again, I’d use the distilled/tap mix, or distilled with some cal/mag only, and use cal/mag with your feed, too. So far so good, and you’ve got a great bunch of growers on tap pretty much 24/7 here.
I’ll definitely try everything you suggested!
Thank you so much for your advice! @elheffe702
Also, is there a good ppm/ec chart to go by? And is monitoring the EC numbers important or just focus on the pH and PPM?
TIA,

Let us know how it goes! You can even create a journal if you like, and when you post updates, pics, whatever, folks will hop in with advice, and you’ll be a pro in no time.
Except you could prob get by right now with just added magnesium (plain old Epsom salt). Def plan on cal/mag in the future because of the water you’re using.
When you can. The epsom salt has no calcium. There will be some from the bone meal in your soil, but you’ll want to get ahead of the deficiencies if you can…proactive rather than reactive. These gals get hungry when they get bigger!
…now I’m thinking it’s something else in Happy Frog, something more renewable, but I can’t remember what…anyway, the goodies in the soil are probably starting to be depleted.
Welcome to the forum. That doctor teals has lavender and spearmint in it like @Drinkslinger noted make sure it is plane epsom salt. I use a generic Walmart brand.
This is the pH chart that I use.
Below is a post @BobbyDigital did yesterday, it is a very good guide for ppm. As he stated if your nutrient line does not have a feeding schedule published use this as a guide. Fox Farms does have a schedule developed if that is who you are using.
It was oyster shell I was thinking of, in the Happy Frog. Anyway, yes, I would definitely get cal/mag. They will need it with distilled water, for sure.
