Leaf tips are browning, strange spots....

Soil grow - 2 Parts MG organic, 1 part Pro mix, 1 bag perlite, 1 cup pelleted lime, 2 cups bone/blood meal.

AN VooDoo juice
AN B-52
AN SensiZyn

Water as needed, I check the weight of the bags, as well as the bottom of the bags for dampness. Top soil is dry as well. I calibrate my pH meter every week, and they get only solutions pH'd to 6.5 on the nose.




It's only on a few leaves, could be nothing..... the plants certainly look healthy otherwise...

You spend a lot on some really good nutes skip the Miracle Gro or whatever you're using try some ffof .When I tried to add all them addivites I burnt it too now I'm just using Sensi A & B with voodoo juice, B-52 and Big Bud it looking alright? How many ppms are you feeding?

Can't get FF here.... I won't be using it again, if that means anything. lol I used pro-mix last time with extra lime and perlite added.

Not sure how many PPM actually don't have the meter for that... really need to pick one up.

Anyone seen anything like this before?

Looks like magnesium deficiency. Look at pictures in sticky posts and I think you'll agree. The darker green veins with lighter green in between is the tell, your first picture looks like it could be the poster child. Other possibility is Zinc deficiency but magnesium is a much more common problem, so I'd assume that first. There are lots of posts on the forum about using epsom salts to add magnesium, or you can use dolomite lime (which also has calcium) if you're plant is in soil. If you buy lime though, make sure its dolomite which has pH of 7. The other limes are very alkaline, and some are time released pellets.

looks like mag deff to me. what strain is it.is it a white strain. also you're using the an range. so you would be better of using there sensi bloom cal/mag. but remember less is more with this stuff. i never go over 200 ppm for ww in coco and white strains do love secondary nutes as much and more as there npk and i never have a problem with mag or calcium or iron. just remember to much calcium from the cal/mag can look out youre potassium the most mobile macro nutrient. so less is more.

u can use eggshells to(not a instant fix thou). Epson salts are the other best way to go

Agreed, looks like something to do with nutes

op could un answer a few q. as im finding it hard to believe that there is not enough mag it that medium from the nutes and any left over from the mg. so maybee lock out idk as it look like mag but ummm..
what water are u using and what strength nutes i know u dont have a meter but what ratio will give some idea. e.g like 1 mill a liter and feed every other day ect. also u have no signs of any other over fert really from what i can see. also u have a lushes green..

  That is your problem. Only water for a few days.​

One thing it might be is the Lime pellets.... if it's turning my nutrient solutions alkaline as it makes its way through the soil, it could be a lock out.... I'm exceptionally thorough with my Ph tester, but that doesn't mean much if the lime is changing the pH mid way....

I use regular tap water (chlorinated, but left to sit for 48-72h before use).

I've been hammering the plants with nutes every 2 days, full strength. I'm going to back off a bit and see how they fair....the next 2 waterings will be straight pH'd water.

I use 4L milk jugs for mixing,
16ml Sensi AB each,
8ml Bud Candy,
8ml Bud factor X,
8ml Big Bud
8ml Voodoo Juice
8ml B-52

That's the ratio that I mix it at.

well.........with line-up, its not a deficiency.......lol. i feel like a thief when i grow with rabbit shit, compost, and EWC. $$$$lotsa nutes there$$$$$$

Might be a lock out I guess.... I don't see how with Organic soil, a huge lineup of AN nutes, and using regular tap water will get me a Mg def.... but that's sure as hell what it looks like... : \

I'm going to test the run off next time, and if need be I'll raise the pH of the solution I water with to ensure that the actual medium itself stays at 6.5pH....

 

[Beefbisquit]

I'm giving them straight water @ 6.5 pH for the next few days to see if the problem corrects itself...

Talked to the guys in the local hydro store who told me to make sure the plants weren't sitting in the run-off water.... something I didn't know! The run-off water can be >3000ppm because of the salts/nutes sitting in the bottom of the bags/buckets and when the plants sit in that run-off, the plants can get burned, or locked out (chlorosis/necrosis) and start showing 'rusty' spots, similar to a Mg deficiency!

i put my bags up on bricks to assure drainage. good decision with the straight water, imo. consider organic. i have a worm farm, and a compost pile, and my nutes are free. just recruiting for organics

That's a good idea, I might have to get a few bricks myself!
