brown edges, yellow spots, red leaf stems

[sliderman001]

I'm growing indoors with a hydro setup. I'm using FloraNova products. The
plants look great coming out of the veg stage. But after a month in the
bloom stage the upper leafs edges get brown on the edges and the tips
curl about a 1/32 of an inch upwards, the leaf has yellow spot and the
leaf stems turn deep red. This only happens on the upper part of the plant the buds look good and taste fine it just seems something is wrong. Is
there an mineral or something that needs to be added. you guy are the
experts I've never had this before. I wait for your answer.

hey there...I'm no expert but that sounds like potassium deficiency to me.

Supposedly they are supposed to curl downwards with that, but all the same...if you are noticing the yellowing and necrosis towards the edges first then spotty patches between veins, and also the stems of older growth being dark red...I'd say that's potassium def.

It might be that you have to much salt and its locking out the K, and I guess this can also happen if your grow gets too cold (i think this is what happened to me)

Hopefully someone else will post with a more definite answer, put some pics would be the best bet...

or mg... The only way to trully know is to do resirch... Google the problem that you have and at the very end type marijuana. You will get some awnsers. Its really hard to tell what it is without pics to look at.

Yeah, I was concerned about Mg too, but will that cause the red stems (so far I haven't found that)

Heh, you use the same google technique I do
