Plants are growing outside in 7 gallon pots. They are about 5 weeks old. I noticed about 1 week agoo some on the lower fan leaves were turning a bit yellow, and they seem to be getting worse now.I am slowly seeing it creep up the plant so now some of the higher fans leeaves are starting to get the same look. I phed using 2 part soil and one part distilled water to get a ph of 5.9. I gave a foliar sprays with epsom salt at 1 teaspoon per gallon, but I am not seeing any improvement. I just fed again this morning with a micronutrient solution that included mg thinking this is my problem. In pic 2 you can see bug damage as well, dont know if that is contributing to the prblem or maybe that is the problem. any help would be appreciated.
Smart enough to know better. Strong enough to do better.
5.9 is very acid fr a soil grow. get it to 6.5 - 7. Use 2 table spoons baking soda dissolved in 1 quart of plain water instead of your usual fertilizer or water in your next watering rotation. use only plain water for 2-6 days and they will most likely improve with no more difficulties, as long as you monitor the acid source.
I am going to be needing to water again so instead of 1 quart can i say make 1.5 gallons and and just go with 12 tablespoons of baking soda instead? also foes it matter if i use distilled water or should i go with tap water?
i dont use distilled or purified water. as long as your municipal water isnt absolute crap your plants will like it well enough. shit, in the wild they get their water from streams swamps and bear piss. even san francisco water is better than bear piss.
I get my water from an underground aquifer. I think it is phed at 6.5 give or take and low 100's tds. will the baking soda have a lasting affect or is it rather a quick fix? I was looking into dolomite lime. only lime i have access to is granular and i heard it takes awhile to take affect.
baking soda is made of sodium and carbon, which are unstable and in the presence of an acid, they break apart, creating sodium metal, and raw carbon. the sodium joins with available chorine/choramine to make table salt which is toxic to plants in high doses, but normal and harmless in small amounts, and the carbon joins with oxygen to make carbon dioxide this is why baking soda bubbles when mixed with vinegar or any other acid solution.
Table salt is sodium (a shiny metal that burns in contact with water) and chlorine (just like the bleach in your laundry room) together these two toxic materials that can KILL YOU IF SWALLOWED! make ordinary table salt which you need to live.
the woody plant material in your soil is being droken down by bacterium, and tannic acid is a byproduct of the digestion process. this stuff is used to make skins into leather, and can turn a plant into a dead pile of leaves. many evergreen trees make the tannins so that any plant growing near them will die off and not be a competitor for nutrients and water. sadly when you buy potting soil, its made form a mix of plant material including tannic acid producers (cedar, pines, spruces, oaks, junipers, etc etc etc...) and if not completely finished composting they continue to make tannins in your flowerpot or garden, making your soil acidic and barren.
with municipal water PHing out to 6.5, eggshells and dolomite will break the acid down and make co2 for your plants, but you could also grow the fuck out of some blueberries! I'm taliking a 5 gallon pot producing shitloads of the biggest sweetest blueberries you ever seen right on your patio. you know you want this homey. dont even try to front.
