6,000 Watt Room Help (pics)

Hey Dudes,

I'm almost finished setting up a 6,000 watt sealed room and I have a few questions regarding the room and the current plants I have in Veg. Here's the setup: (this is a Prop 215 grow for our medical patients in California)

Veg Room
2 4ft 8 bulb T5 systems - 24 plants

Been vegging for a month and a half in Empire Builder Soil

Strains:

- Fire OG
- Banana Split
- Purple Cadillac
- ACDC CBD
- Suzy Q CBD

Veg Nutes:
- Earth Juice Nitrogen
- Earth Juice Microblast
- Superthrive
- Earth Juice PH up

Feeding PH 6.8-7

These are in 2 gallon pots and getting ready to put them in 10 gallon Smartpots with FFOF & perlite for flower.

I've always used Happy Frog and never had any deficiencies in Veg but the hydro store was out at the time so I went with Empire Builder. The pics are the plants now. Does anyone have any idea what deficiencies or PH problem this is? I've been growing for a few years and can usually fix problems but these I can't figure out.

Either the PH is too high or I am under-feeding. I am using 5 gallon jugs to hand water and they've been vegging for a month and a half so I'm using about a Tablespoon per gallon of Nitrogen and Microblast. Any help would be appreciated.

Flower Room:

We just ran electrical for the 6,000 watt sealed room, I might dimmed the ballasts down to 3,600 watts for the first couple runs.

I have a 24,000 BTU mini split and the lights are air cooled so the carbon filter with CFM fan will be positioned outside the room.

Will I need a dehumidifier for this? I've heard Yes and No on this. It might take a week or 2 to get the Co2 tank. Will this harm the environment if it's sealed without the Co2 for a little bit? What are the precautions of being in the room while the Co2 is running?

Thank you in advance.

Don't know how big your room is but my sealed room is 20x12 I run 2 dehumidifers to keep it all good at 45%. Without my dehumidifers my rh goes to the 70's+

I was told not to seal my room without c02. I've never run without it sorry can't help with this one.

Where are your lights being vented from? From the pictures looks like they will be pulling air from the room?
As for the plants looks to be a nitrogen deficiency... Whats the PPM of feed solution? And pH is a bit high... 6.2-6.8 is optimal for soil.

The Flower room is a 8x11 kinda tight. The air will be pulled from outside the room thru the carbon filter > ducting > to a T split 3 lights on each side > out the ceiling. You're probably right on the PH too I read that Boron can't be absorbed if the PH feeding is above 6.5.

As far as dehumidifier goes it is always a good idea to have just in case but I suggest looking into VPD (vapor pressure deficit)

Since it looks like the deficiency started from tops makes me think that is a micro def., Maybe iron maybe zink., A little calmag def too caused by a lockout

N def starts from bottoms so thats out of the question

Are u checking your runoff ppm? Do u think u might have a salt buildup causing the lockout?

Thanks for the replies. It might be salt build up as well. I water with nutes every 5 days every other watering with plain water. The runoff I haven't checked for a couple weeks but usually it's good about 7.

Maybe that's too high

Dont worry about the ph, worry about the ppms. If youre over 1400 ppms in your runoff your in some shit. I do a quick leach if i get over 800 coming out.

Your going to love my picture analysis lol. The first plant pic looks like magnesium deficiancy to me. Second looks like wind burn. Third looks like lower leaves not getting enough light. And i was going to mention that you may want three t5 setups in veg instead of two. And the last picture looks like the you have stopped feeding for a while after you got a little burn, and now theyve started to yellow. Now ill read your post lmao.

K after reading id say it could me macro nutrient deficient. If your only giving N and micros, it could be lacking the others. Does your micros have magnesium in it?

Also you will need a dehu. Two 70 pts at least. I run a 170 commercial and a 70 home depot jobbie and still have problems in portland with all the winter rain.

I agree with @Alienwidow.

Isn't there an earth juice grow? With a balanced NPK?

Looks like pretty severe K deficiency. Someone please correct me if I am wrong.

Lol thanks!! I'm pretty sure the Microblast had Mag in it, I'll double check when I'm back at the location and let u guys know.

I feel like every time I start nutes I use 1/4 strength per gallon and then the next week 1/2 and so on and they always end up with deficiencies.

With organic nutes it is important to kinda plan ahead as the elements need time to break down to be usable by the plant.

Many suggest 100% of the schedule for them.

I do not however. i use Pure blend pro grow. I only need it in flower. I start at 5 or 10 ml and feed every time. But if I see curled down leaves or yellow tips I back down the EC the next watering. If it still worsens I lightly leech the pot with a gallon of clear well water and then add a gallon of a lighter feed which attracts and cleans out more extra salt buildup.

It's organic but all bottled nutes seem to have this issue. Just part of container gardening.

Forsure. I use Pure Blend Prob Bloom for flower too. I'm gonna try upping the nutes and wait for them to respond. After transferring to FFOF I've always waited a week or 2 before adding nutes because the soil has a lot to begin with. Is this recommended?

I use pure blend pro grow. The bloom is terribly unbalanced for a potting mix grow. Too much phosphorous.

Oh wow didn't know that. I had problems with my last grow using it. I only had that grow up for 4 months before I had to move so I couldn't dial in nutrients perfect.

I just tested the runoff and its 6.9

I gave up dialing in nutrients, PH etc. I have 2600 WATTs HPS in 8'x8' x8' tall room. Built in garage, insulated walls and ceiling, 14000BTU AC neutral pressure, fans, and High Reflectivity index flat white paint, Sealed lights 6" Vortex fan, draws air from floor of garage outside room and expels out of room. So, I use Advanced nutrients, PH perfect Connesieur Line master grower level. 4gallon pots, Fox Farm OF and Happy Frog blend of soil. Yes its more expesive than other lines. I pushed out over 3 LBs trimmed perfect bud, 12 plants, Blueberry headband and Strawberry fields strains, not high producers by the way. Advanced Nutrients cost me maybe $125 more than some cheaper ones. Plants were amazing healthy. Using RO water and AN nutes I dont check anything, I just feed them. As I approach 4th week of flower I start feeding more often, I never change ratio of nute mix. I have had much larger rooms with more lights but I am now retired living in smaller place. Been growing since 1967. Indoor growing for 12 years. Plant pics I saw of yours looked like, leaf burn from dripping strong nute mix on leaves, chlorosiss - leaf yellowing, variety of reasons, usually magnesium deficiency, root problems too. High temps and humidity can throw everything off.
