No, the magnet won't work. Flushing helped though, I'm sure.
Sweet is not a nutrient. It's an additive that if overused, will kill your ladies.
The necrotic spots sound like possible overwatering issues, which can lead to root rot. Let 'em dry between flushes, waterings and feedings.

Leave seedlings alone (properly ph'd water only) till 4th or 5th set of leaves. You'll kill them otherwise. No additives, no nutrients, no sprays...

Some believe in the practice, but I've seen no evidence it's worth the effort. Perhaps it's strain-dependant. I'm guessing it likely changes the CBD:CBN ratio, but am doubtful it is doing what everyone is wanting the darkness to do. (increase trichomes)

I've even seen some that put 'em into darkness for a couple of weeks. :wtf:

That's the main problem with wives tales...too hard to prove, too hard to disprove...so it must be true in the eyes of the blind believer. :thumbsup:
