PURPLE Stems?
Lime is only bad for plants when it is overapplied or raises pH up out of range. However, 2 tablespoons in a party cup is WAY too much! Re-pot right away into something larger with fresh soil. If there is any lime left on the surface, scrape it off. Do a runoff pH check and adjust it if necessary.
I would use caution watering in a micronute with that high Fe content at the strength the bottle recommends for lawns and shit, especially since you have the possible Ca overdose (from the lime) thing going on.
The biggest reason IMHO to keep a quality micro supplement around in a soil grow is to help keep the plant from getting worse when you see that you have a nutrient uptake problem in the root zone, by foliar application, while you work on discovering the SOURCE of the problem, and fixing it.
Since a correct one-part fertilizer appropriate for cannabis DOES contain micros, most soil growers won't have to add a micro supplement to their fert solution. Yours doesn't, so you'll need to do that, but go EASY on it! I would use less than the bottle recommends. That's a good chunk of iron in there!
