Hello, OG Reekn help needed

[DRVYBZ]

Hello,

I am having problems with this plant and cant figure out what is going on. The leaves are curling and they are starting to turn light green to yellow. I'm attaching a couple of photos to give you an idea of what they look like. My other none Reekn plants are doing just great in the same setup. Can't figure out if they need something extra. If you have any experience with this strain, any help would be appreciated.

Welcome Dr. I see magnesium def. Here's the write up in the plant problem solver. The light color between the veins in the leaves told me.
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 tell... the green veins along with the yellowness of the entire surrounding leave is a dead giveaway, but sometimes that's not always the case here. In case you have one of those where it doesn't show the green veins, sometimes leaf tips and edges may discolour 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 colour, 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 can'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 soil... 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 . (Wouldn'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
(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 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.

Picture one shows a mid grade magnesium deficiency.

Does it look like it's similar? I have a hard time with pics.

 

[DRVYBZ]

thank you very much for that. I will get on that right away and update this thread on how things went.

Yes, it looks just like the photo that was posted. My other plants look great so I guess the reekn is a bit more greedy. I will post an update on how things went. Thanks to everyone for the assistance.

Ok. Good, let us know.

I tried to upload a video but the site doesn’t allow that extension. Was made with iPhone. I’ll Have to snap some photos later. Thank again for the help.

You guys really helped me with the cal mag problem, now this is starting to happen to my leaves. My ppm was at 550 so I diluted it with 20 gal of RO water. It started off looking light nute burn but now it’s looking a bit different. Any further help would be great. Using current culture nutes ph is at 6.0 at the moment. I’m letting the system circulate the fresh water I put in at the moment.

I think I may have over did the cal mag.

I meant to say I diluted with 10 gal of RO
