Looking to bulk up my roots

I run the general hydroponics flora line and mammoth P in a 24 plant 5-gallon bucket flood and drain system with a 200-gallon reservoir that I change around every 2 weeks. This plant Vegged for about a month and a half and is nearing 2 months in flower. My water temp was 63F the whole veg but has been at 66F for the rest of the time because I read that was more what they like. I vegged and flowered under 6 1000w phantom DE’s that we’re 600w for veg and 825w dying flower. My room is at 82F so I don’t think i can bring my lights up any higher until I install a mini split to compete with the heat. I have around 2 inches of standing water that’s sits in the buckets between feeds. Any advice on how to make my Up my foot production?

How's the plant look

I’ve had mites that I battled all harvest with a few different projects so I’m sure that effected development but this one was actually one of my biggest and most resilient. Probably 4-6 oz.

When I grew DWC a couple years ago my roots in a 3 gallon buckets blew these ones in my flood and drain away.

Roots are kinda irrelevant if the plant is healthy and big

Those roots look pretty dark...not looking great

Bottom of the plant

Southern AG will give you explosive root growth.

Those roots look terrible. Next run try using southern ag garden friendly fungicide (same as hydroguard but more concentrated). The roots should be white, not brown.

Are my dark roots probably root rot or some sort of nutrient lock up? Is the southern ag strictly a fungicide or is it also mycorrhizae?Ive been wondering if I should use something additional to the mammoth P like great white or something

Yes. It's killing your yields.

SAG GFF is one bacteria (Bacillus amyloliquefaciens) that is commonly used in other products like Tribus and is known to help prevent pythium (root rot). The Mammoth P is a different group of 4 bacteria (Enterobacter cloacae, Citrobacter freundii, Pseudomonas putida and Comamonas testosteroni), mainly helps uptake of phosphorous.

TBH most of the best hydro crops I have grown over the years were only fed base nutes and calimagic. Thats it, nothing else, no bennies, mycos or other fancy bottles like floralicious or b-52. I think that the best place to start, only base nutes and calimagic if using RO water.

Roots are never irrelevant, yields can suffer greatly while the plant appears "healthy" up top.

I was definitely thinking I should be focusing on my roots a lot more this next grow because that seems to be where my trouble starts and then it seems the mites come when the plants are weak. I don’t know if I will use less products this next run just because I’ve already got a grand plus in nutes but I was thinking about using significantly less. Like tops 850ppms mid to end flower. Maybe look into cutting some unnecessary bottles out once I run out lol.

100% going to invest in the SAG you mentioned

Mites suck, usually they come in on yourself. Always change clothes, perhaps even shower before going into your grow room if you have been outdoors. The other most common cause is bringing in plants from another grow or outside.

I keep mites out of my grow rooms by not bringing them in myself.

I would stick with only GH Micro, Grow, Bloom and Calimagic and the SAG GFF for the next run. Sterilize all your equipment really well. I like to put some Physan 20 in the system and run it for a while, then drain and rinse well.

Physan a res-clean kind of product?

The mites always seem to be the death of me. I can get my plants to the end and pretty much always with some nice looking bud but I can’t remember a time I didn’t constantly battle with mites. I’m mid Harvest right now and am determined to keep my mites at bay from here on out since I just stared a perpetual. I’m going to commit to spraying once weekly, deep sanitizing between crops, and trying some different methods like sulpher sprays in veg and predator bugs in flower.

P.s thanks for always responding. Been appreciative of your advice and trying to implement some new things.

I avoid a perpetual where you can't have an empty flowering room to clean really well. Perpetual is perfect for perpetuating a pest problem. I would fix the pest situation before even considering a perpetual.

It's strong stuff, don't get the concentrate on your skin. I mop with it, clean equipment with it, even dip clones from other grows using a weak solution (1 teaspoon per gallon).

I have a couple of seeds popped and cuttings but otherwise I haven’t started the actual cycle yet. Like you said kind of trying to do my best to neutralize then stay consistent on spraying and keeping clean.

Well get the veg room clean of mites and keep it that way. My veg room is like fort knox, the most secure and sterile room of all since it houses mothers. If the veg area has mites at all then you will constantly have issues. If it's sealed up from outside then the only way mites are coming in is on you, your buddies, pets, plants. So nobody need be in there but you and like I mentioned don't go in there if you've been outside and could have mites on your clothes. I keep a pair of house shoes for my grow room only, don't wear shoes I have been outside doing yard work in. lol

Back in 2012 / 2013 I was consulting for a commercial grow out here in Colorado, they were stubborn as fuck and rarely listened to my advice. They never got a crop out of their grow, in what ended up being about 18 months of operation before they went bankrupt. I warned them about being clean. The owner had a fella that was poor and would do any odd job cheap, dude rode around on a moped and would even work for a sack lol. He would be at the owners home running a weed eater, then roll into work go into the grow room and start watering plants with clothes still plastered with weed clippings. lol Yeah they had mites, duh.

I also warned them about growing bag seeds, hermies and all that, bag seed is there for a reason. Well the owner had a shoe box collection of all the bag seeds he had saved up over the years, some really good strains he said, thousands of beans. Well they shotgunned a shit ton of them, it was 700 some odd plants they vegged, filled up a flowering room with them and were only watching for the typical male balls to cull males. One day they asked me, what are all these little flower looking things laying in our trays below the plants? I went and looked, sure enough, banana peels everywhere from a shit ton of bananas popping, yellow dust everywhere. At least 50% of the plants had busted bananas. I showed them the bananas still on the plants, the piles of pollen laying on the fan leaves and sugar leaves of the now 5 week flowered plants... Whole room full of seeds, not a small room either. Fuckers were trying to sell the seeds lol Like seriously, sell hermie seeds to folks? Dick move. Between mites, hermies/bag seed and powdery mildew they never got a run out of their massive grow. Fuckers coulda made a fortune if they had only listened to my advice. Everything I told them would go wrong did.

So you this specifically to clean with? I was reading on the website it can be used as a foliage spray and added to hydroponic systems as well but I’m not sure that would benefit me.

I use it mainly for cleaning, but I have on occasion dipped incoming clones to make sure they weren't carrying spores. The dilution rates are different for cleaning or foliar use. If you were to add it in a hydro system it will foam up so I would imagine you need an anti foaming agent of some sort.
