Greenpoint seeds!!

[Big Green Thumb]

3 plants in the 5x5.
The plant up front is my OBS#3 that REEKS of orange and acetone when flowering. This gal is at 6 days 12/12.
Back right plant is Copper Chem #2 at almost 6 weeks.
Back left is OBS #5 at almost 4 weeks, that has a mellower orange/cream smell when finished.
These plants are in hempy buckets being fed the same Jacks/calmag/Recharge as my others, including the plants vegging.

So, I've got a spot in my basement I'm gonna build out after the new year some time. It's 6'x12' and I think I'm gonna use 6x4 for veg and 6x8 for flower with a 4x8 canopy.

Do you guys see any issues with having my fresh air come into the veg room and then exausted into the flower room and then back out? It stays pretty cold year round down there and I'm trying to think of a way to keep the temps up a bit when the lights are off without wasting power on a heater.

I'd just run old school HID lights and recirculate air inside the basement during the cold season.
You might want to invest in a charcoal scrubber to control odor...

Maybe you guys can help me out with this OBS #3. This plant has these spots forming on lower leaves (my CC had this too). I added 3 ml of calmag per gallon to try to combat this when it happened on my CC and maybe (?) it helped. This OBS started it while in veg and it isn't getting any better. This plant is growing in 100% perlite, getting Jacks 3-2-1 (3.6 grams-2.4 grams-1.2 grams) and 3 ml/gallon of calmag. Ph'd to 5.8-6.2, fed nutrients every watering. Please help!

Oh you're good then man. I used to do that very thing you're talking about in my old cribs in Illinois. Winters there were brutal so you had to use that heat from the lights or else you're heating bills/gas bills get real out of hand fast.

If you have a natural gas furnace in the basement it will help add co2 in the environment as well, if I'm not mistaken. Most goes up the vent but some stays.

Thanks, that's reassuring.

You're running you ph a little high for hydro so I'm guessing it is lock out cal or mag. Try running your ph 5.5-5.8 range and bump that cal/mag up to at least 5ml a gallon. I think that will help out.

I ran into this same issue because my ph in coco was up in 6.2-6.5 range because my pen was broke and the drops just didn't give me an accurate reading.

Yeah charcoal filter for sure. I'm debating on either building 4 lights with hlg 320's and the Pacific light concept strips, or just hanging 2 630 cmh's

Also I would suggest running a more balanced nutrient solution for veg. Imo 3-2-1 is lacking for strong veg growth, I like it to be closer to like 3-3-3 or 4-3-5 or 5-3-4 but closer to even. Hopefully it's all gravy buddy

Have you calibrated your pen recently? Is it a good one or a cheapie?

Those 1000w hps lights eliminated the need for extra heat in the cold of winter many nights.

Hell even now I typically just have the lights for heat in the grow room, no need for heat.

Cheapy, but I splurged on a big bottle of calibration fluid that I use every few weeks or so to dial it in. It is usually within .2 when I calibrate it.

That is what got me. My probe on new Milwaukee pen went bad and wasn't reading right then quit working altogether and then those damn drops left too much variation in color to ever give an accurate reading.

Not sure if you know that 321 isn't the NPK ratio, it the ratio of Jacks-cal nitrate-epsom salt. Don't take offense if you did know this, just want you to know what I meant. Jacks 321 is pretty well proven to work.

Although I do like the CMHs, I would go with the boards.

Buy another cheapie or a nicer one and see if it's the pen?

Also, the 5x5 is currently running at 800 watts.

I'd go with CMH for the IR and UV -- and it sounds like you need the heat.

Do you agree ph should be lower? Or good where it is?

Never grown in hempy buckets so can't say. I don't have much recent hydro/chem experience tbh. I've not done more than a full light in coco/water in many years.

I think that your ph should be closer to 6.2-6.5 with the exception of real hydro due to ph swing. I've run GH 6 micro/9 bloom at 6.2ish in coco with great success.

lol, my bad bro. You're good then. I thought that was the npk numbers.

I've always read hydro you want more acidic for the chelated nutrients and in soil more base.

5.5-5.8 in hydro like dwc etc.. but I do this for coco too.
Then 6.2-6.8 range for soil.

But if you had success in coco in 6.2 range then I can't argue with results. I just usually go a little lower.
