Benzelsanswered grow question 3 years ago If you grew this yourself, you would know roughly what it could be from a short list of options. Then make the call on what to do with it.
If you got this from someone you know, you should be able to ask them for same result. If your asking us Im assuming U cant ask the person you got it from or they dont know. So now its an un known substance= rule 1 for un knowns is no stop dont. lols. Dont touch it as It could be anything from pesticide to herbicide (they often dye plants to be seen by the person applying them) But its not like pple spray anything good on em either is it? Or even go around spraying harmless things on them...
Ive never heard of pink seeds b4 either so doubt its natural. Id avoid. U could plant the seeds to see what happens, but i wouldnt expect alot. Its just not worth the risk to consume it in any way.
