Dying, crispy leaves

OutdoorGrowin · Mar 10, 2020

What's up everyone I currently have some plants flowering indoors under LEDs and everything's going well so far except three of the plants are having some problems with the leaves. Not sure what this would be from so any input would be greatly appreciated.

K/Ca/Mg/Mn/deficiency.
Although your other plants are doing fine they are eating different things and different rates.

Shake the plant and check to see if there are any white bugs flying around.

May be to much magnesium. Causing a salt build up and the plant to eat away at the lower leaves to get the energy to the top of the plant. I may be wrong but mine did something like that. I cut back on cal/mag and it helped.

How often do you feed them, remember less is more, i used to feed the shit outa them but figured out i actually was doing more harm than good, how long into flower?

Thanks for all the feedback, I only feed them once a week with some fox farm. They've been flowering for somewhere around a month.

A few pics of the healthy ones.

The way the damage to your leaves looks is exactly like my plants looked when I got whitefly's. If you have them if you shake the plant you should see a bunch of white things flying around. Pests go for weak plants first, so you always have some plants that look great and then some that look bad.

I don't think you are dealing with a nutrient issue, but that's just IMHO. I think it's possibly a pest issue. Or depending on what your temp and humidity is it could even be fungal. I'd remove anything with brown on it.

I shook them earlier today and didnt see anything flying around. I was thinking it could be some sort of mold or fungus also but I have a dehumidifier running at all times so I don't know if it would be.

Shaking my plats to disturb the whiteflies worked much better outdoors, I could see them flying around after shaking. Indoors, with white walls, I didn't see hardly any at all after shaking. They are very small.
