My sativa strains were always red stemmed until I started supplementing with Magnesium Sulfate (Epsom).
It really works. The sulfate is great for the terps too.

@Highlanders cave based on the smells, bud growth and experience this far I’ll say that I most anticipate the ecsd followed by gmo this round. I haven’t snapped any gmo in a bit but she looks like there’s something wrong with her compared to the other ones right now just because she’s a long flower compared to these. She is starting to fill in though and will be worth shooting soon. BOnions is delish and I must say I was getting sad that the jar is running out. It’s interesting, there’s a little hint of something in it that reminds me of the p10 I used to have of yours.

ECSD got the axe today. I dry whole plant, picked off the remaining fans but it was close anyway. 9 weeks was about right though I’m sure10 would be good too, the heads look good and the space is needed, it’s a damn jungle in the shed. GMO needs at least 2 weeks, it’s just starting to bulk out so maybe even 3. BOnions wants another week, one more week will bring out her funky side, I find it’s more grape at 8-9 but 10-11 she get a musty arm pit backend with a hint of onions. It’s just delish! Also hits like a train when taken this far. The buds just get harder from here. Larry says to me that she could come down but another week would make her happier!
I’m washing down the room and getting it ready for gorilla glue, OG 18, chemdog D, and cluster funk. Oh man I am so looking forward to this run! Been trying to get these going for a minute. These are some of my all time favorite genetics, my mouth is watering just thinking about it. It’s going to be a funktastic time en el punto right here.
This smells so freaking good, ecsd:

Well it’s drying too fast so I broke it down a little to swap into a tote. Temp is at 70. I took the tote in the house to watch tv while I trimmed stem, that was a mistake. I don’t usually like to smell up the house, this batch is far stronger than I noticed in the shed. Whew, she stinks so good the whole house reeks and the wife is stressed, I did well! I just wish the bud was ready. Taking down BOnions on Monday, probably let Larry go 11-12 with the gmo. I’m anxious to start the next run. I have some seed projects that I want to start too. I think I’m going to take a risk on a $500 pack of road kill skunk. I’m sick thinking about it.

8 weeks update:
Showing some mag deficiencies, still trying to find the sweet spot for additional magnesium in the medium to compensate the leds. Still, they are ripening quickly and look to produce well so dialing in isn’t too far out I don’t think. I’m shooting for 9-10 weeks on these as the tricks are filling in and milking out. Already seeing some amber on the leaf resin! ECSD looks most ready followed by BOnions then larry.

Despite the mag def, looks great...I'm trying to find my sweet spot with mag as well. When running a bunch of different strains I find it is the most common problem

I’m still pretty green with the leds too. I want to try lowering them a bit. I feel like I can get more swollen. I used quite a bit of magnesium as well from a few sources, I have read the leds will cause higher consumption, it’s obviously per pheno. That’s my first run of that plant I’ll have her better next run. I might take her to 12 weeks and see how developed she’ll get, shoreline says it’ll keep ripening and packing it on for secondary harvesting.

With LEDs the light is more intense. It is also missing the UV associated with HIDs.
The plants react by making more leaves to protect the plant.
Getting the distance right on the LED lights took me forever to figure out. Higher is better and a light mover makes things even more amazing.

Another thing that was hard to figure out was the watering schedule. The LEDs don't heat the plant like the HIDs did and the water doesn't evaporate as quickly (not a problem if you are in hydro). Because they drink differently, they also eat differently.

So many variables!

Ya it took me a bit to figure out it was based on the actual surface temperature of the leaves that was at issue there. I have uv mixed in at tested levels with a mix of 80 and 90 cri chips. Also ir to achieve correct surface temperature. I was getting heavier foliage with more uv though, when I leaned it to red more like hps is when it balanced out. I think there is something to the uv that regulates magnesium intake somehow. Also, I’m not running cob or lensed chips. They are strip builds combined with logic pucks so the light is more diffuse. These are “white” & “soft” 5k and 3k with just a few adjusted spectrum diodes. I just want to max the ppfd and since I can’t afford one of those fancy meters I’m going to trial it. The crap meter I do have gives me relative data, when I go outside it pegs my meter @1200, I figure if the intensity doesn’t do that it’s probably not enough. At mfg height for the chilled I get just under, which on my meter says 760 ish which for a crap meter Is probably not that far off. Anyhow I can hit those numbers but it’s in the 12-15 inch range. I have seen some dudes on here with similar setups get colas like outside, that’s my goal! I’m a tryin’!

My set up is wall to wall there’s only up and down but they all dim in sections too. There are two 200 watt panels on the ends that each have 9, 2 foot strips 3:1 2k:5k and the middle is two 315 watt fixtures tied together, (one ballast on the logic pucks and one running 6, 4 foot strips 1:1, 3k:5k but the sequence is stupid on those, I was in a hurry and the application I built it for at the time wasn’t effected by it, still the intensity distribution is even. I will update that in the near future. I swear though when there was enough uv in there to stop mag def everything gets super leafy, I didn’t like that so I’m thinking of just figuring out the offset, maybe just some royal blue leds?!

Hey cowboy whats the good word mango. Well I got the go ahead last night to turn the downstairs bathroom into a grow room. And my gf is going to foot the bill lol. I guess she feels a little guilty since I turned the big grow room into a bedroom for her family when they visit. The Anne Frank closet just isn't going to cut it for what I have going, it's not big enough. The bathroom is not being used, needs to be replumbed. so i'll gut it and start from scratch. It's 6.5' x 6.5' not huge but should be ok.

Open to any and all suggestions from everyone here. Been doing some research on leds, thinking I will go that route this time. Talk to ya man!

I don’t know if you remember a dude called whitewiddow, it was something like that? He used to hang around, anyway he taught me about led and how to save some money on them, he is a sparky. There are actually a few legit U.S.A. companies that give discounts for diy kits too.
Man! Happy day!

So I have been thinking, maybe that mag issue is because I’m trying to balance the spectrum at a given intensity, what if the intensity needs to be in the red spectrum and the presence of uv in relation is ancillary? Perhaps it’s just that simple, that by providing a ratio I’m inspiring the deficiency! I know most people just assume a magnesium “tax” which I’m getting the hang of, it just seems odd to me. Seems like there are many theories, There are two that seem to make sense to me, one is that because of the lower temperatures the plants don’t transpire as quickly which causes a slow down in those elements transporting through the plant. The only issue I have with that theory is that you theoretically couldn’t correct it by adding more to the medium, so it seems that they are using more in actuality. I use both oyster shell flour and crab meal to season the soil so theoretically I shouldn’t have calcium deficiency ever. If I see that I know ph is drifting. Another theory that seems more well founded is that the skewed spectrum causes a higher demand for nitrogen which is supported by cal/mag presence. I have noticed a higher demand for nitrogen through flowering, which combined with the new formula for happy frog dry nutes I stopped using it.
It’s kind of exciting like when i first started growing.
Man on a side note I got some nug from the dispensary the other day and I found some spider mite webs up in there!!! Mother fuckers!!!

Yup , store weed SUCKS! Don’t waste your money. I would like to sell mine here in OK but I would have to pay for. $ 2,500 Licence to sell to the dispensaries!! What Bull Shit!! I am going to call and see how much they pay for a pound. It might be worth it but there are no guarantees .
i have gotten 2emails on recalls from weed Companies that have had excessive amounts of pesticides that were on the shelves at the pot shops here in OK. I think I could really do well with my product. There are so many scandalous growers out and about. But I would feel like a loser giving money like that to sell my stuff. They should be paying me!!

Ya, it pisses me off. They are all of the sudden offering $10 grams which is cheap around here. They also selling their lesser bud for like 8, the 12-17% stuff. Should have known. Their bud has been on the decline and now unscrupulous ethical practices selling that crap to people. it’s a sketchy med scene here for sure, there’s no competition in the market so bad product and no pressure to correct it.
Oklahoma is a total shit show, that mess will catch up to them sooner than later I think. Completely opposite, there’s very little reg there, but similar result just better pricing there. That license you’re talking about is like $18,000 here and they aren’t allowing any new producers so it’s just for making products from already produced cannabis and to get the license you have to have a board approved source of raw product prearranged. Eg, no new business here until they get the laws fixed.

What kind of root zone temps do you have bud? I’ve theorized before that the root zone temps are effected by the LED use along with the leaf surface temps from not having the IR. This inturn causes transpiration issues and deficiencies.

70-75 degrees at the root, 85 at the leaf. I was having transpiration issues when I first switched until I got the temps situated. They wouldn’t drink! I messed with the spectrum since then and my experiment yielded less mag deficiency with more 5k strips but the plants stack tighter and produce as much as double the leaf. Buds were smaller too! I’m also copying from growmou5e as I got some of his pucks to start with and scaling that spectrum up is basically the dealio. I learned what I know from whytewiddow here, I think he left the site but he used to hang out in our friend group. He helped me learn how to build them and gave a baseline to learn from.
Nearest I can tell no one has remedies for the mag deficiency showing with led use, I feel like I exposed a contradiction in that if cal/mag support nitrogen intake and more foliage Is produced with blue leaning spectrum, without bumping up the magnesium in the soil, how can it be directly tied to mag uptake?
I feel like I might be tap dancing around the answer. To get the stems to green back up and get a more even leaf fade I had to add a bit more than double the magnesium than usual. Perhaps it’s as simple as just using 90cri chips or better to get more of the ancillary spectrum that we apparently take for granted in observable growth characteristics?
Thanks for thinking about this with me TC!
