epsom salt dosages to fix def?

[pizzadude]

i was curious as to what dosage to fix these def, seems like epsom salts will do the trick?






moonshine mix, under 430W hps, top two picx 3-4 weeks 12/12, bottom in veg. ph'd 6.1-6.3 waterings with bubbled tap water.

moonshine mix

What all is in this? Seems like it has tons of dolomite lime, bloodmeal, bonemeal, etc... Epsom salts ain't gonna' help them bottom 2 photos. Unsure about the top photo. Have you tested runoff ph? What ferts have you been adding in your water and how often?

Edit: I think this may be a case of adding too much stuff at planting and then guessing as to what to add that's deficient. I call bs on moonshine mix.

here's info on the mix

never checked the runoff(i water with 6.1-6.3ph bubbled tap water, 15-20% runoff), but will today. and never fert'd them cept for some hygrozyme and superthrive rarely.

Ocean Forest
Planting Mix (guano/castings)
Light Warrior
Black Gold
Coco Brick(small brick)
1 cup peace of mind (for flower)
2- 5 gal buckets worth of perilite....

Did you follow this exactly? That piece of mind fert sounds more intended for using out in your yard somewhere not in a potting soil. I don't know what to say...your now guessing as to what to add and when. In the future, I suggest using promix plus some added perlite and 3/4 teaspoon powdered gypsum per gallon of mix. Then add npk plus micros in your water. No guessing.

Your plants are nute burned, I would flush or transplant into a lighter mix'. You don't need to add that much of anything. A dose of Epsom will hurt if anything. If you too lazy to do any of that get your water PH higher than 6.1-6.3...after all the salt it runs through it will drop like a mofo, WHAT IS YOUR RUNOFF PH?

P def (see sticky)

The edges all around the leaves or half of the leaves can be brownish and work its way inwards a bit causing the part of the leaves to curl up in the air a bit. Fan leaves will show dark greenish/purplish and yellowish tones along with a dullish blue color to them. Sometimes the stems can be red, along with red petioles that can happen when having a Phosphorus deficiency.

thanks everyone for your input and help, P is definitely off.

Soil

Phosphorus gets locked out of soil growing at ph levels of 4.0-5.5
Phosphorus is absorbed best in soil at a ph level of 6.0-7.5 (wouldn’t recommend having a ph of over 7.0 in soil) Anything out of the ranges listed will contribute to a Phosphorus deficiency.

Hydro and Soil less Mediums

Phosphorus gets locked out of Hydro and Soil less Mediums at ph levels of 6.0-8.5.
Phosphorus is absorbed best in Hydro and Soil less Mediums at ph levels of 4.0- 5.8. (Wouldn’t recommend having a ph over 6.5 in hydro and soil less mediums.) Best range for hydro and soil less mediums is 5.0 to 6.0. Anything out of the ranges listed will contribute to a Phosphorus Deficiency.

Like I said, check your runoff, your PH is most likely wayyy to low... depending on how low you might need to flush it to stabilize the PH, thus helping the lockout.
