Brown spots on leaves

[Newbud420]

Hello,

got some plants (my first grow) in week 8 of flower - growing in soil.
Started seeing these little brown spots and I can’t work out if nute burn or cal mag deficiency ( or maybe something else)

Any advice is appreciated

I knew that Big was gonna say that. That is his pick up line on Colfax.....he is right though....just doesn't work on girls.

I always politely ask the girls if they would like some of my organic cal-mag

Hahahaha I’ll give them some now then see how it goes.

Thank you for your help

Seriously that is your problem. The leaves that are already effected need to be culled. They will not come back. The new growth will be fine. 7 1/2 mill per gal.

Just saw you are in the 8th week of flower....how long do you plan on running them. Might be to late already. If so they should be fine until harvest.

They actually are looking like they are pretty close to harvest....might just be better left alone.

My plan was week 10 so 2 weeks -

I’ve just put some cal mag with some water in and I’ll strip leaves off with the spots tomorrow when lights back on.

It’s an organic grow so plan to use nothing but water from now

No cal/mag necessary if only two weeks out.

Won't hurt nothing at this point.

I’ve already put some on, will it be ok?

 

[WeedHopper]

Yes. I feed my girls Mag right up to chop. They love it.

 

[Newbud420]

Ok great thanks for your help

 

[user 60570]

give some,of that cal-mag....don’t be afraid....your plant will quit up taking cal-mag when it wants to

i tried injecting some cal-mag with a syringe into the plants veins and the plant loved it.....however , I caught her selling herself at night hooking up on Colfax to support her habit...

but yeah , she loved the stuff

 

[boo]

you're such a sassy character big...

Hi, I'm having the same problem. Is it a huge no-no to use a Cal-mag supplement with nitrogen during flower? I'm using Sensi Cal-Mag Extra with 4-0-0. I fed with 2.5 ML last night but hated adding the nitrogen. I figured it's better to add a little nitrogen than to have a huge deficiency with calcium/magnesium...

I also have Dyna-Grow Mag Pro which is a magnesium supplement made for flower. (no calcium) are these symptoms more Calcium of Magnesium deficiency related?

You shouldn’t have that much longer to go if you are in week 8 of flower. Some of my leaves got a bit knarly at 8 weeks but it didn’t effect the end product I don’t think anyway… I quit giving cal mag and everything else at 8 weeks tho

I think your plants will enjoy the calmag but it won’t help at this point
