Is this Calcium Def?

[JEMman]

Hello all, and thank you ahead of time. My plant is around 30 days old and almost all of the tips of my leaves are like a yellowish brown color. The pic of the leaf that is yellowing out is at the bottom of my plant.
I originally thought that it was a magnesium def. so I gave it some epsom salt in a foliar spray. As I've looked a little more into it, there seems to be little yellowish brown dots forming on sum of the leaves. So I was thinking it could be Calcium def.

Don't know my soil ph but have fed with only 6.3 ish water throughout. And haven't used any nutes other than one tea with wormcastings and molasses.

There are also a couple of yellow burnish looking spots on the outside of a couple leaves that I tried to capture as well.

It sure is. The small spots are anyhow. The bigger ones are likely a mag def starting.

Time to cal mag that baby.

Dang... so how about organicare's calplex or something like that. I was told that it was the organic way to go. Cal-Mag im trying to stay away from this round I had the botanicare version but heard that its not good for the myco's. Or how about if I just top dressed some dolomite lime? Or would that just take too long?

I have a bottle of cal max which is by no means organic.

Check your bottle of molasses. Mine is high in both cal and mag. I put in a tbl spoon of it into my teas. Seems to keep it from progressing when i see it.

Okay, I have the regular old Grandmas... but I think that that when I was at the store I saw another version that was called Brers or something like that and it had almost double everything mine has. Think I'll go get some of that and water some molasses into my next watering. You use 1 tablespoon to the gallon?

 

[Northern Grower]

The is the one i use.

I would say a tbl spoon to a gal will be good. I do that for about 4 liters. I don't exactly measure it. Just about that.

 

[JM]

yeah that should be good... a tsp of epsom salts will help boost mag too... i find they are mag hogs during flower!

I've been hitting them with a lot of cal and mag and was wondering if this was all from the same deficiency? The leaves are just dropping off on the daily. Ph'd water is given to them at 6.5 so I didnt think it would be a nute lockout, but i dunno really. Don't have a soil meter that works

JEMman, look at the images on this link. As stated, there are signs of cal/mag deficiency. The last images you show look like a phosphorous def. link: http://www.autoflower.org/f7/basic-deficiencies-list-11.html

With all that going on, it doesn't seem unreasonable to think about nute-block. If it were me, I would do a good flush, at least twice as much water as soil mix, and then watch for a couple days. Doing the flush won't harm anything, even if it doesn't fix it. But, with as much as it looks like you have going on, I'd at least like to do a re-start. Just my
