Sun Burn, Nute Burn, or Deficiency

For a while now I've had what I thought was a deficiency in my plants, and tried to remedy it with their feeding and ph adjustments, but it hasn't gone away. They are all outdoor.
Ive been using a custom soil mix based on kellogs patio plus organic with coco, perlite, epsom salt, dolomite lime and a dash of sand. I also mixed in some Dr Earth powder bat guano with microbes, which is 10-3-1. For feeding i've been making AACT with Dr. Earth tomato, veggie, and herb fert which is 5-7-3 with mycorrhizae. Realizing this had more P than N, I began to supplement with AN Mother Earth super T. Ive also added additional dolo-lime and epsom salts to some of the teas to try and fix apparent deficiencies.


Last week my GSC plant got burned in the high heat we've been having in the Bay, or so I thought. Its been in a shady area since the day of the burn, and I've been watering it when the pot is lighter. Since then i've been wondering if it is in fact nute burn.

Also the my hash plant is showing signs of a combination of deficiencies, which I've also been trying to treat, but i cant decide if its N, Ca, Mg, Phos, zinc, or other.

And finally a plant i've been growing from seed has off and on shown signs of being N deficient and possible Ca. Ive given it lots of bat guano, but it seems to be continuing.

Any advice/help would be appreciated.

first 4 are HP, second 4 are GSC, third 4 are rando from seed

That looks like a Mg def. I think you locked out the Mg by adding too much lime. I think there is a proper Ca to Mg ratio. If one is too high or low, it affects the availability of the other. You should scrap the epsom salt and use just lime. Lime has enough Ca and Mg in it. Hence lime = CaMg(CO[SUB]3[/SUB])

0: Scrap all the current soil amendments
1: Flush with ph'ed water
2: Get some happy frog all purpose 5-5-5 and apply once a month. Use that tea, it will break the fertilizer down faster.
3. Water when needed

my pH is between 6.5 and 7
but what about the sun vs nute burn
there are different types of chlorosis and necrosis going on with the diff plants
im sure one of them is either sun or nute burned but idk which

you need to take care of them mate, they are hurting, move them all to some shade, let them recover.

i grow hydro but it sounds to me like you have as said above been adding way too much to try and amend your soil, i would say that with all your mixing and the teas, you have fucked the soil, to be blunt.

i would transplant to some normal potting soil, that contains very weak and balenced nutes (n-p-k 5-5-5 or summin)

and hope that it will correct the imbalance you have going on now.


whenever i do dirt plants i just plant them in good soil and leave them they hardly ever need feeding. im sure you make soils amended with ALL addatives before the plants go in, then they can just use what they need.

also as soil is so slow and holds onto everything i dont think you can PH it i might be wrong on this !!

Damn Brah!! sometimes less is more. I grow both soil and hydro, and it seems to me that u have a little too much going on in ur soil. I would transplant to a new medium. Remember these plants are pretty tuff they can grow without a lot of help from us. So only give it what it needs. Don't get me wrong supplementing trace elements into ur plants diet is a must but, just don't go crazy with it. Good Luck and Happy Smoking :bigjoint:

adjust your PH to 5.5
pull out all the burn and yellowish leaves
reduce your PPM to 400
the heat and high ppm i think its the reason
