I Also Tested My Ph In My Soil Today Finally Lol Both Of My Ph In My Plants Soil Is Between 6.4 - 6.6 So That Seems Like A Good Range For Ph In Soil.
Here Are My Plants, The First One Is A Month Old & The Other Is 3-4 Weeks Old. What Does It Mean When Some Of Your Marijuana Leafs Turn From A Dark Green To A Lime Green On The Sides Of Sum Leaves?? Because This Is Happening To Some Of The Leafs On My Oldest Plant And Idk If This Is A Problem Or Not...The First Pic Is My Oldest, The Second Is A Example Of What Is Happening To Some Of My Leafs On My Oldest Plant And The Last Is My Youngest. The Oldest Is 8inches Tall And The Youngest Is 11inches Tall.
u have a magnesium deficiency. to properly test your ph,do a run off test.put a container under the pot u have your plants in.flush with plain water until u get run off in the container below,test the ph of the water in it.
Magnesium (Mg) - Micronutrient and Mobile Element
Magnesium helps supports healthy veins while keeping a healthy leaf production and its structure. Magnesium is significant for chlorophyll-production and enzyme break downs. Magnesium which must be present in relatively large quantities for the plant to survive, but yet not to much to where it will cause the plant to show a toxicity.
Magnesium is one of the easiest deficiencies to tellâ?¦ the green veins along with the yellowness of the entire surrounding leave is a dead giveaway, but sometimes thatâ??s not always the case here. In case you have one of those where it doesnâ??t show the green veins, sometimes leaf tips and edges may discolor and curl upward. The growing tips can turn lime green when the deficiency progresses to the top of the plant. The edges will feel like dry and crispy and usually affects the lower leaves in younger plants, then will affect the middle to upper half when it gets older, but It can also happen on older leaves as well. The deficiency will start at the tip then will take over the entire outer left and right sides of the leaves. The inner part will be yellow and or brownish in color, followed by leaves falling without withering. The tips can also twist and turn as well as curving upwards as if you curl your tongues.
Excessive levels of magnesium in your plants will exhibit a buildup of toxic salts that will kill the leaves and lock out other nutrients like Calcium (Ca). Mg can get locked out by having too much Calcium, Chlorine or ammonium in your soil/water.
One of the worst problems a person can have is a magnesium def caused by a ph lockout. By giving it more magnesium to cure the problem when you are thinking you are doing good, but actually you are doing more harm then good. When the plants canâ??t take in a nutrient because of the ph being off for that element, the plant will not absorb it but it will be in the soilâ?¦ therefore causing a buildup. A buildup will be noticed by the outer parts of the plant becoming whitish and or a yellowish color. The tips and part way in on the inner leaves will die and feel like glass. Parts affected by Magnesium deficiency are: space between the veins (Interveinal) of older leaves; may begin around interior perimeter of leaf.
Problems with Magnesium being locked out by PH troubles
Light Acid Soils, soils with excessive potassium, calcium and or phosphorus
Soil
Magnesium gets locked out of soil growing at ph levels of 2.0-6.4
Magnesium is absorbed best in soil at a ph level of 6.5-9.1 . (Wouldnâ??t recommend having a ph of over 7.0 in soil) anything out of the ranges listed will contribute to a Magnesium deficiency.
Hydro and Soil less Mediums
Magnesium gets locked out of Hydro and Soil less Mediums at ph levels of 2.0-5.7
Magnesium is absorbed best in Hydro and Soil less Mediums at ph levels of 5.8-9.1
(Wouldnâ??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 Magnesium deficiency.
Solution to fixing a Magnesium deficiency
Any Chemical/Organic nutrients that have Magnesium in them will fix a Magnesium deficiency. (Only mixing at ½ strength when using chemical nutrients or it will cause nutrient burn!)
Other nutrients that have magnesium in them are: Epsom salts, which is fast absorption. Dolomite lime and or garden lime (same thing just called different) which is slow absorption. Sulfate of Potash, Magnesia which is medium absorption. Worm Castings, which is slow absorption. Crabshell which is slow absorption. Earth Juice Mircoblast, which is fast acting. (a must buy!! Has lots of 2ndary nutrients).
Now if you added to much chemical nutrients and or organics,( which is hard to burn your plants when using organics) You need to Flush the soil with plain water. You need to use 2 times as much water as the size of the pot, for example: If you have a 5 gallon pot and need to flush it, you need to use 10 gallons of water to rinse out the soil good enough to get rid of excessive nutrients.
Thanx Man. How Much Epson Salt Would I Have To Add To My Soil To Fix the Problom??? And Does Adding The Epson Salt Increase The Ph In the Soil or does It increase anything else In the soil??
