Need advice on correcting mistakes before it's too late...

[Rusty Trichome]

Geez...where to start...

...growth is stunted and leaves are showing signs of multiple deficiencies....mostly cal-mag and potassium type symptoms

According to whom...?

...I told him it was probably ph and in a panic he dumped a about a cup of dolomite lime per gallon of water solution into the soil, before he tested (I made him buy the soil ph tester the next day and sure enough, ph's are still around 6.1 or so 2 days after the dolomite blast) AND he foliar fed them a concoction including spray and grow+bills perfect fertilizer+epsom salts+a crushed up tums (for calcium he said!)+a teaspoon of dyna gro pro-tekt

Keep your friend away from the garden. One way to stress the ladies beyond all hope is to add shit without knowing why, how much, or why not. Never add anything not intended for the garden unless you enjoy torturing your plants. Especially if uncomposted, uncooked or otherwise not in a form the plant can uptake. Tums, coffee grounds, eggshells are common mistakes in container gardening, as is epsom salt overuse. Uncomposted garbage in the container takes too long to break-down, interracts with other chemicals and compounds that the fertilizer supplies, can swing ph wildly, can cause pathogens and rot, and by the time it starts breaking down to usable components, the plants have been long-since harvested.

Cannabis is a weed and can take a bunch of abuse, and still grow. But if you keep shooting your thoroughbreds in the foot with every mis-diagnosis and ill-concieved treatments, your results will smoke like a weed.
Till you get really good at diagnosing your ladies ills, likely best to fill-out the CanCom troubleshooting form whenever necessary, and let an experienced gardener help.

...so now we have some plants drenched in this concoction, sitting in soil drenched in dolomite lime-laden water....I was about to tell him to add wood ash, but now I'm thinking all this crap has been done to them I dont want to complicate things further

Wise afterthought. :thumbsup:

...should we just wait and see what happens...or should we flush w clearex (and foliar rinse with distilled) right away? OR.... should we go all out and transplant into decent potting mix mid flower?

I'd transplant them asap, and hope for the best. The shit that has been added won't magically disappear and can cause problems in the near future.

...And then what...? The buds look small but nice (maybe even a bit too mature and crystalized for their size...) but many of the plants are totally pale green/yellow with burned blotchy and twisted leaves that don't look capable of photosynthesis, while others are still nice and green with bigger buds. My inclination is to go drastic, simply shake off the root balls and transplant into nice new conditioned potting mix and hit em with a high nitrogen organic veg fertilizer to maybe set back the clock a bit and try to replay the last 2-3 weeks of flowering.

Personally, If all this info is correct, I'd flush the crap out of 'em, (3-5 times pot volume of properly ph'd water) and then let the rootball dry-out. Wet rootballs fall apart, which isn't good. If you remove all of the potting soil, you lose the rootball structure and when you replace the soil you will break, fold, spindle and mutilate the roots. Once dry or semi-moist, I'd carefully massage-away as much of the old soil without doing any damage to the roots, and re-plant in a quality container potting mix with perlite in it. (a larger container would be nice, if possible) Water with properly ph'd water, and resume normal feedings per manufacturers instructions the next scheduled feeding day. No extra's, no mega-doses of anything, no concoctions or sprays...nada. Just watering and your nutrients. In about a month I'd start small doses (1/2 teaspoon per gallon of properly ph'd water) unsulfered molasses. This provides calcium, magnesium, iron, and carbs. A solid replacement for CalMag Plus and all carbo-load products.

This is where it get's tricky...from this point forward, pretend you know nothing about diagnosing your plant's ills, and post your problem and situation here before any real damage can be done. I can respect taking initative, but I respect common sense more. :jointsmile:

And keep in mind...fixing your growroom ills is a process, not an event. Treatments take time to show results, so patience between steps is mandatory.
