Looks like a phosphorus deficiency. If the nute stength is OK (1400), the pH could be off, locking out P. What's the pH? What's the nutrient? Been adding any Mg (Epsom salts)?
Nicotine may work as a miticide, depends on if your mites are heavy smokers, they may already be resistant or addicted.
There's better miticides, try Avid. Nicotine itself is not carcinogenic. The carcinogenic culprits in tobacco are tobacco-specific nitrosamines (TSNAs), which are formed in curing and burning tobacco leaf.
Yep, that'll do. I'd reverse the direction of your exhaust blower and put the carbon filter up in the attic to save space in the grow room. They're kinda bulky.
Most strains come to about the same height in SoG, finishing at about 40" max from the media surface. The amt of vert height you need in your room varies depending on how tall your watering system is, but figure you need at least 24" clearance for lighting above the tallest plant.

yeah i was planing to make the vert. height something like the diagram in the pic. it would make it easyer cause i would only have to build 1 shelve.but to be able to fit im gonna have to change up the shelves so i can make more vert. room.
should i run extention cords out of the door to a power strip?the pic is just like a basic thing nothing to detailed.for my clonebox i have a 48in fixture already i have to order two bulbs though you think thats gonna be enough light for my clones? i have a list of things im going to buy and i want to make sure im getting the right things.do you think i would have enough light in my flowering room?looks like i have to smoke a couple bowls and redraw the picture for more vert. space..so how much more vert. space you think i need to add?

also im gonna get two 100gal dual output tetra whisper air pumps.im gonna have 1 airline connected to 12 in. airstone inside each 18gal bin.and the mothers will have a 60gal dual output pump to connect to two 12in airstones inside their 18gal bin.is that enough air for each bin?..the only one that would be almost full of water would be the 0-2 week bin.all the others you can just fill halfway right?
theres gonna be 4 plants per flowering bin.how many mothers should i have?
is this a good heatmat for my clones?

o what size rockwool you use for your clones?
HydroWarehouse Online Hydroponic Superstore
would these fans be good enough for intake and exhaust for my closet?
thanks for all the help.

according so some simple numbers he has already, your pic doesnt work. Youll need to ditch the mother being in the same box to have all the room you want.
Shouldnt be a big deal to use another box for a single mother though.
I have designed several systems similiar to yours and all of them are easier drawn than built. I hope you make it work for you.
Hi Al, if I have a highly alkaline medium (rockwool) and I'm in 'drain to waste', should my nute solution be more acidic in order to maintain a accurate ph at the root zone?
I made the mistake of adding some rockwool that was not soaked long enough and it causes my run off ph to be a complete point above what goes in. My res. is at 5.6 and my run off is at 6.8. I think this has caused a lock out with significant signs of deficiencies.
I approached this by flushing the medium with the rest of my res., I was doing a change anyway so I just used it to rinse the medium. It looks a lot better now, form 5.6 going in to 6.1 coming out, but I could bring the ph down a little in my res. to like 5.3 and then I would have a run off of 5.8.
What do you think?
Thanks,
Unity

Sorry, this needs a total rethink. Not nearly enough vertical height. With a flood system, plan on at least 6' floor to ceiling to make room for the watering system, plants, clearance between plants and lights and some room above the lamp to act as a 'heat sump' where warm air can collect before being exhausted.
Extension cords and power strips may be used but they MUST be HD rated. Look for 'suitable for air conditioners' on the labelling. Don't exceed more than 80% of the rating of the extensions i.e. no more than 8A continuous load on a 10A rated extension. Power strips which include a circuit breaker are a very good thing.
Clones don't need to be pounded with light- that's why we use fluoros. Yes, the 48" fixture will do fine, but a 24" would do.
Yep, a 400 will do nicely for a small grow.
Lots.
Imagine for a moment what I think when I run into some poor underinformed sod who wants to grow dope in a PC case. Utterly hopeless. The very last place on RIU you will find me commenting is on PC case (and Aerogarden) grow threads. You can't convince these wishfuls that it won't work and I just won't waste my time on them.

hey Al...quick question for ya...I just built a bubble cloner and was talking to the guy at my local shop...he suggested I raise the stems above the water level and just let the bubbles pop on the stems...now here is the question...if I do that, wouldnt I be basically making it and aero cloner?

^^hahaha.has anybody done a pc grow?i bet the plants look like mini mes..im gonna have the mothers in a diffrent spot.the flowering room will be in the closet and the clonebox on top.did you read my other posts?

hahaha.i think its harder to draw it out.it will work 1 way or the other. im just getting all the info now after i got it all planed out im gonna order all my stuff and take a trip to the hardware store..

should be fine.
You'll be surprised at the amount of mist you'll get from a big bubble curtain's small air bubbles breaking the surface of the water. You may not need to keep the levels as high as you're planning. However, more res capacity is generally better than less, up to a point. Undersized reservoirs suffer from nute strength instability. EC ppm will jump up if the water is removed from the nute soln faster than the nutrients themselves. The result of (nute soln - water) = increased concentration of nutrient per volume of water. Oversized reservoirs have very stable pH & ppm but are wa$teful in that more nute mix us used than the plants could possibly eat.
how many total plants in flower? A good, mature mum which has been pruned back once or twice (or has donated a couple passes of cuttings) raised under HID lighting (either MH or HPS) should give you 5-8 good thick stems every 2 weeks.
Looks OK, can't really tell much about how it is made. My heatmat is moulded in silicone rubber and is fixed at 30C. It was not cheap- about 3x the price of the economy mats. I haven't seen one like mine in some years, but the silicone rubber type is the way to go if you can find them. Mine's been plugged in & running 24/7/365 for the last 8 years. Many heatmats are made of much less durable stuff.

40mm.
Your ventilation system should be able to shift the volume of air in your room in 3-5 mins. A 500 cu ft room needs a minimum 100CFM blower. I wouldn't go that low unless there were cooltubes shifting the heat from the lamps. 167CFM (500cu ft/3min) or more is suitable for a 500 cu ft room. I don't know how big your closet is in cu ft so I can't really tell you if the 250CFM 6" blowers are sufficient, but I suspect they are.
Yes, you can do that but be verrrrrry careful. After running at 5.3 for a while, the acidity of the solution may react with all the residual Ca dust in the RW and cause your pH to overshoot low. One day your runoff may be 5.8, but as the Ca dust is all reacted with the phosphoric acid in pHDown, your runoff may drop right down to 5.3, meaning the pH in the rootmass is 5.3, which WILL cause you some grief. I think I'd prefer to flush the media with a large volume of pH 5.8 water with no nutes until the runoff pH comes down to 5.8, then go back to business as usual. Will prevent shooting low.
Yep!

Drawing up a proposed arrangement is a very good thing to do.
If you fail to plan, plan to fail.

oh good heavens, they're all over RIU like a bad rash! One thing they all seem to have in common is a lack of photos showing grand and glorious successes.
What, you have something different planned to this image you posted?
This is the arrangement that I was commenting upon that I believe needs a rethink. If you have other plans, why'd you bother posting this?

haha so true..well should i get that heatmat thats the only brand they have.im not sure what temp it runs at.how flexible is the temp of your heatmat does it have to be at 30c?
heres a new pic.
Al B. Fuct

30C is the magic number. Most fixed temp mats run at 30C.
Just make sure you have room for 40" tall plants and about a 24" gap between the tops and the lights.

yup..can i use 1 inch rockwool for my clones?

25mm cubes? I think those could be a tick small. They may have a tendency to dry out faster than 40mm. Stick with the 40mm plastic wrapped cubes.

Hey Al,
Many thanks for taking your time to share your expertise-
I posted this in indoor growing, but specifically would like your input as well. Mind taking a look?

well shit al that might be why i failed at your method...i was using the 1 inchers....very hard to get them just right ...they were either super dry or soaked...even with the corner watering....i wonder if that's why i failed?
