Transplanting large plants started in their current, large pot, need advice.

Hey guys, thanks for reading. I'm currently having a lot of magnesium troubles with a few ladies I have growing in some 7 gallon aurora root pots and want to x-plant into 10 gallon pots with super soil before I flip because I've got the feeling this soil mix is just going to keep giving me trouble, so fuck it. They're on day 77 today. For the record I'm indoors, but keeping it to 2 ladies/light to keep the count down.

My concern is that I STARTED these ladies in their current 7 gallon homes (from clone) and I've read that plants put into giant containers straight off like that will tend to send their roots out straight to the bottom and sides of the pot, filling those areas first and the center of the pot last. If this is indeed the case I'm afraid when I pop them out the whole root ball will just collapse, costing me the majority of my root structure. Does anybody here have any experience transplanting ladies in similar circumstances?

No I run nothing over 3 gallons here and I run hydro. But if you let your pot's dry out a little the soil or soilless will stick together and not fall apart as you transplant them. Anyway I'm sure someone with far more experience than I will be along shortly

Just make sure she is dry and the pot feels light. We just did a few big ones and it was hit and miss. The first pre98 was still a little damp and the majority of the roots sheared off when we tried to move her. The second grape was totally dry and went to 15 gallon without an issue.

I think that after 77 days in 7 gal pots, your root system should be sufficiently developed for transplant - what kind of pots are you in? I personally would not go from a 7 to a 10, that's a very small upgrade for such a large plant - I would go no less than double that size for ease of transplanting alone. if you only have a magnesium problem, it's theoretically fixable without needing to transplant - a 7 gal should yield nicely inside.

See, I've always read to do it wet, and had good luck doing so with smaller pots but I've never done something this size and I can't imagine lifting and turning over these 7s all soaking wet. They're stressed so they hate getting really dry but they'll live.

Honestly I'm pretty sure it's more than a magnesium problem. I had a magnesium issue that I finally zapped about three weeks ago, that held them back alot and it was the typical chlorosis on the margins going from the tip in, top down, was exacerbated by the lights being within a YARD. Now three weeks later they showed signs of recovery for a couple weeks but suddenly the new growth chlorosed big time at the margins, but also throughout. It's still at the top and seems exacerbated by, you guessed it light, and I've got mine in air cooled hoods at a YARD. With all that, these ladies aren't as big as I'd imagine they ought to be, unfortunately I can't upload images. Spaced out two a light I've still got 40-50% of the canopy to fill up once I lay down trellising, which is good because the extra veg time will help burn off the N in the SS.

Currently they're in a 1:1:1 mix of perlite:EWC:harvest moon soil with spikes of dry organic amendments in 7 gallon aurora root pots with a 4" layer of composted steer manure & perlite amended with greensand, kelp meal, oyster shell flour and GRP. The idea is that the soil's microbial population will populate the "spikes" (holes filled with a mixture of dry amendments) and the plant will take from them as needed, which seemed to work for a month or so, until it didn't. Right now the plants, except for one precious lil lass, are "half-healthy"; the bottom leaves are in perfect shape except for a millimeter of yellow on the tip from a strong tea, wheras the top half are chlorosed and clawed downward. Again both the lights are minimum of 36" up.

So I'm fed up. Super Soil has a reputation of being idiot proof and certainly has all the nutrients the ladies will need.
