I’m sorry bro I know I’m a pain in the ass but wassup with the Epson salt should I do that to?
You are not a pain in the ass, bro. lol Totally fine. Epsom salt is awesome. It’s one of those cheaper ways to get magnesium that I was talking about. It also delivers sulfur, which is critical to cannabis in small amounts. It’s pretty hard to overdo it, but I might top dress with a tablespoon every other week or so. If you’d rather mist, you can dissolve 1 tsp in 5 liters and water or mist your plants with that, too. (fyi an Mg deficiency can cause yellowing leaves. it’ll be interesting to see if some epsom makes that whole plant get greener – i’m betting it will.

Both Epsom salts and Cal-Mag supplements are used to address nutrient deficiencies in cannabis plants, but they serve slightly different purposes:
Epsom Salts (Magnesium Sulfate)
- Primary Use: Provides magnesium and sulfur.
- When to Use: Ideal if your plants show signs of magnesium deficiency, such as yellowing between leaf veins.
- Benefits: Easy to find and affordable. [Good for late flowering stages when you don’t want to add extra nitrogen]
Cal-Mag Supplements
- Primary Use: Provides calcium and magnesium, often with a bit of nitrogen.
- When to Use: Useful if your plants show calcium deficiencies (e.g., brown spots on leaves) or if you need both calcium and magnesium.
- Benefits: Comprehensive solution for calcium and magnesium deficiencies. [Some formulations are nitrogen-free, making them suitable for various growth stages]
Choosing Between Them
- Epsom Salts: Best if you only need magnesium and sulfur, especially in the later stages of flowering.
- [Cal-Mag: Better if you need both calcium and magnesium, and potentially some nitrogen, depending on the formulation]

great info! glad you shared this!
so what light schedule should I put on them
I need to know much more about your whole environment. Aren’t they under 12/12 lighting already? From when, to when? I would recommend staying with whatever lighting level you’re currently at. For flowering cannabis, it should be pretty close to 12 hours of light per day. I literally have the timer on my lights set some that they are on about 11 hours and 45 minutes a day – from about 8:30 a.m. to 8:15 p.m. It’s the total amount of time under light – which, during flower, should be slightly under 12 hours.
I have mine 845am and down at 815pm
Yeah, buddy, that’s perfect. Just let them stay right there!
FYI, keep in mind, sometimes there are real advantages to keep them ON overnight and OFF during the day. I do this sometimes because electricity is cheaper at night. On the other hand, I don’t like having a ton of appliances running at night, either.
So to recap the overall “flow of the grow”. . .
- when they’re seedlings, I do 16/8 under a humidity dome, 85 - 90% RH, maybe 300 PPFD. You are building root zone and RH is their primary way to drink, so RH must be high.
- after about 3 to 4 weeks, I do 18/6 with no dome, closer to 500 - 600 PPFD, 60% RH. More light, slightly less humid. They start growing above the soil more now. Too much RH cannot hurt them. No buds to worry about getting moist.
- as veg progresses, I may move to 20/4, closer to 700 - 800 PPFD, 60% RH. I’m trying to pack on vegetative growth. I tend to take about 7 weeks from seed to flip day. (I believe plants really do need a rest, so I rarely do 20/4 and NEVER do 24/0 to push veg. I don’t have any hard science behind this. Many do grow 24/0.)
- when I flip to flower, it goes 12/12 (about) and I’ll start to move it closer to 1000 PPFD over the next few weeks. I drop RH slowly as the buds develop.
- this time of year, I watch temperature and humidity super closely to keep them close to a VPD rating of just over 1. I’m gonna link to the chart I use
- finally, as I get closer to harvest, I keep humidity low-ish – 35% RH is good. Why? I don’t want the buds too moist because of mold worries, etc.
This is why I don’t grow outside in Oregon. When photoperiod seeds are finishing outside (like right now), Oregon gets too cool and wet in the fall to finish without making special arrangements (a cheap tent to protect them, etc.).
I grow in a 4x5 tent in my garage, which is sorta my “lung” room, right? It’s garage air that gets sucked into the tent, AND the expelled air goes into the garage too. The garage temp and RH tend to be BETWEEN the house temp/RH and the outside temp/RH.
My personal challenge right now? At night in my garage, it gets colder – say, 63F – but the humidity goes way up naturally at night, so RH is closer to 60%. That means my VPD is out of whack. I can’t really dry it out (I have no dehumidifier). So I actually keep the temp closer to 75 with my space heater in the tent. Then, the VPD – the balance of temp to RH – is better.
Does this help?

I grow in an outdoor shop as well.
I run lights at night to use the heat, off during day 
I think the hardest part is the final stage lol I have to shape and cut the buds I was thinking of using terp bags have you ever heard bad things about them bc the whole burping darkness it just sounds like a headache

Yes, the temp is fine but the VPD is off. See it says 2.25? You want to just a bit over 1.
Bump your humidity up a bit, to around 55%.
You see that 2.25 number drop.
This matters because a good VPD means the plant’s stomata are functioning properly, which means your whole plant is healthier.
FYI, I am just using that chart I sent you to figure out the appropriate VPD.
I am still new, too – but when I was VERY new, yes, simple was better. I still try to keep the whole process as simple as possible.
Some people love growing and want to be busy all day, tweaking every little thing and optimizing and doing TDS readings on their water, etc. etc. That’s fine. It’s a fun hobby!
But I want to do only the core stuff that gets me 80 or 90% there. If I’m spending more than about 60 - 90 minutes a week on my 4 plants, that’s fine.
I also watch my costs, and try to spend my money where it will really matter. Gaia Green ferts is a good example. It’s expensive stuff. But I’m also not buying all sorts of bottles of other stuff. I’ll supplement with one off stuff as I need to, but good food and clean, PHd water are the most important things.
This, my friend, is worthy of separate study.
Yes, you can grow the best weed ever.
If you screw up drying/curing, you’re done.
Right now, start thinking about how you can maintain a single environment that will be:
- Dark
- 60 - 65 F (no higher than 69)
- Humidity constantly around 60%
- With good airflow, circulation/breeze, etc.
This is what is required. I’ve tried to dry/cure in numerous ways. Here’s a tip: just try to figure out if you can make your tent do this.
FYI, if your tent runs at 75 F and/or is too dry or too humid, you will seriously damage your crop.
Seriously. Use those specs above that I gave you. You have time to figure it out.
dude the little one in the bucket is the most stinkiest of all of them I want that one to get tall
Are all the plants the same age? As in, were they all flipped to flower on the same day? Assuming they were. . .
they are all different ages one thing I didn’t do was write down the age I was new jumped in and took a chance
If they’re all regular photoperiod seeds and were flipped to 12/12 on the same day, then they’re all in flower.
They’ll all be stretching a bit more, and if they are different strains, they will all stretch varying amounts.
Each should have its own net over it (like the one you just did). I personally put all my plants under the same net (that’s what me and myfriendis410 were discussing above).
But yes, everything I said yesterday about how to fix up your big plant to the net and put it all on the same horizontal plane? That is now true for all of your plants.
If you need to use blocks/books under your pots to lift them up to get them level, I would recommend doing that.
If you don’t want the other ones to flower just yet, they need to be under something more like 18/6 – which means a different tent or room, with different equipment. If they’ve been in 12/12 lighting for a week or so, don’t bother. Just let those little guys flower, too. Switching them back to 18/6 after they’ve been in flower for a week will not be helpful.
do you know which jacks everyone keeps talking about?
