Root damage should be kept to a minimum if possible, but as long as it's a small percentage of damage all should be fine.

It might be that at some point down the line they (the plants) will want you to resume a 'normal' nutrient regimine, but i'd stick with molasses only till they've recovered from the transplant shock and previous 'issues'.

What specific soil did you transplant into? Might be enough organics in the fresh soil to take you through to the end with minimal addition of flowering nutrients. Might be you need to add more. Time will tell.

Keep in mind that any stress to the plant can and usually will delay final harvest date. So don't go freaking-out that they're taking longer than the advertisements say...

Are you referring to a b vitamin product for root growth? If so...perhaps you should read this:

No, I don't recommend root accelerators, and rooting hormone doesn't help to form roots on roots. (in case you were wondering...)

No additional additives till they recover. They'll find the good soil without chemical assistance.

Keep ph steady, don't overwater, let 'em heal...and be patient.
Rusty Trichome Reviewed by Rusty Trichome on . lower leaves turning purple-brown hello all! i have 2 plants, both are at the begining of their 5th week of flowering. about two weeks ago i've noticed that in one of the plants, some of the lower fan leaves were starting to turn purple-brown, 3-4 days later it also happened with the other plant. since than, the color spread to some more leaves, but only to the lower/med sections and only to the larger leaves (not to the small ones which surround the flowreing areas). in one plant, two of the purple-brown leaves developed Rating: 5
