Cool Cool Im on it.

In the process of adding the epsom salts now. 16.5 Tablespoons, 16 tablespoons and 1 1/2 teaspoons, however you wanna word it. Sure seems like overkill with the recent addition of the cal mag.

I'll keep updating the pics until Im comfortable things will be ok. Thanks again for the advice, appreciate it.
ITs ''1'' Tablespoon per gallon, and mix it in hot water first dude to disolve it ok.

Am having a read around sites dude and a good few of them are saying its best to put a small pinch of epsom salts in a spray bottle rather than feed them with it, as feeding them with it could lead to other nuits getting locked out. id do some home work on it first if i was you before you use it.

This is from another site dude.

I would not ever, under ANY circumstances, add Epsom salts to my nute solution because of the chance of locking out OTHER nutes. If you are running in correct conditions, there is PLENTY of Mg available in all quality complete fertilizers- unless it is locked out by pH or overfert.

For a quick fix, mix a couple pinches of Epsom salts in a spray bottle of lukewarm water with one drop of liquid dish soap, shake, and mist onto your plants daily until you see greening between the veins.

I assume you HAVE correctly identified that you have Mg deficiency symptoms?

This subject keeps coming up, so.

What are Epsom salts?

It is crystallised magnesium sulphate. It is a naturally occurring mineral that is used by all living things.

Chemical name: Magnesium Sulphate Heptahydrate ( or Hydrated).

Chemical Formula: MgSO4 + 7H2O , (Hydrated Magnesium Sulphate).

Mineral Name: Epsomite (MgSO4 + 7H2O).

Similar minerals: Kieserite (MgSO4 + H2O, Hydrated Magnesium Sulphate)
Hexahydrite (MgSO4 + 6H2O).

Magnesium Sulphate is found in 95% mineral waters! Up to 2% of ocean sea salt is Magnesium Sulphate.

Human body needs Magnesium Sulphate!

This simple mineral is often in short supply in modern grown foods and people are often deficient in it. Raising the levels of it often help to reduce severe acute asthma attacks, its used to manage seizures associated with toxemia of pregnancy. It is helpful with all sorts of muscle contraction problems, also several dysrhythmias problems. Has been used for hundreds of years as a liver cleanser and as a purgative.

When used external such as in a bath, magnesium sulphate is absorbed through the skin, it draws toxins from the body, sedates the nervous system, reduces swelling, relaxes muscles.

As a foot soak: Soothe aches, remove odours, and soften rough skin with a foot soak. Add 1/2 cup of Epsom Salt to a large pan of warm water. Soak sprains and bruises: Epsom Salt will reduce the swelling of sprains and bruises. Add 2 cups Epsom Salt to a warm bath, and soak. Or locally use a warm epsom salt-soaked compress to reduce swelling from scrapes, use a cold compress to take the sting out of insect bites.

Epsom salts are named for the mineral rich waters of Epsom, England, where they were known at least as far back as Shakespeare's day. The salts were originally produced by evaporating the spring water where the mineral occurred.

For plants epsom salts can supply two essential chemicals that they need, ie Magnesium and Sulphur in a soluble form absorbable through both the leaves and roots. At the dilution plants need it, it is also friendly to the soil/compost micro flora and stimulates the micro herd.

Overdone like anything it will cause harm to the soil and its fauna. Like everything its about balance. If the plant does not need it don't give it.

With a large plant outdoors in cultivated soil with a good balance of nutrients will never show/have an Mg deficiency. The reason is that its root system is unlimited, a large plant will have a feeder root mass occupying 1 to 2 thousand litres of top soil. The Cannabis plants use of Mg increases as it matures and will be at its peak at around the third week of flowering on 12/12. A plentiful supply at this time is critical to facilitate the transformation into full flowering mode. Because indoor plants grown in containers have a restricted root mass, this is the time where you are most likely to see a problem. It needs dealing with at this early stage.

With cannabis Mg deficiency shows on the lower sunleaves first, the green between the veins becoming a little lighter green as the very early symptom. Seeing it at this stage means the plants are telling you I need magnesium now! In the picture below on the left shows lower leaves of a plant that is starving and short of all three of the main elements ie nitrogen phosphorus and potash but not Magnesium, on the right show lower leaves short on Magnesium only.

Dosage for misting:

1 level teaspoon to a heaped teaspoon per litre of water.

Dosage for watering:

1 level desert to a heaped tablespoon per 5 litres of water.

Dissolve the epsom salts in some hot water first to make sure it has all dissolved properly.

Applications:

1. As a foliar misting just before lights out. Repeat this every three days until you see an improvement.

2. Use when watering/feeding in compost: Once in the vegetative stage, & twice when in flower (day 10 & day 35).

Ok cool. Thanks again banks.

Never heard of a wee read before, maybe we live in pretty different places.

I'll try foliar feeding with some epsom salt.

I wouldnt go as far as to say Ive correctly identified anything. Thats really the reason I posted this topic. However, theres a couple leading indicators which brought me to such a conclusion. First, my plants look exactly like that picture. Second, only the larger plants show copper spots and interveinal chlorosis type stuff. Third, I just added the nutes a couple days ago and really should have added them earlier, but there were some timing issues.

I had an Mg deficiency with 3 plants. I used the epsom salts foliar feed method, and it worked like a charm. I also used small doses in 2 normal feedings with no problems....only good results. Been back to normal feeding for 3 weeks and almost ready to finish harvesting. The difference is, I'm growing in soil, and I had a high PH at the time. I didn't start with the epsom salts until after I flushed the soil. Good luck.

Banks, you know of any hydro suppliers that ship outside the UK and carry those products? I looked around but it seems that those products are supplied by only UK vendors who dont ship internationally. Couldnt find any other vendors that would ship to my location.


Was doing some research and came up with this stuff. Kinda repetitive but just wanna be sure to diagnose correctly.

Magnesium (Mg):

-Commonly deficient in Cannabis
-Yellowing of lower leaves progressing upwards with severity
-Interveinal yellowing
-Rust brown patches on leaf margins, tips and between veins




Calcium (Ca):

-Affects new growth first
-Terminal buds and root tips die back
-Necrotic patches on margins and near leaf base

These were taken from http://www.growery.org/2991/Diagnosis Again, just want to be sure that Im correctly diagnosing my plant. The problem is that when this deficiency in my plants begins, it looks like the pic of cal def, but as it progresses it looks more like mag def.My problem started from the bottom up so, again Im leaning towards Mag Def. I'll post some updated pics a little later today.

Usually cal and mag defiencies, lockouts, and or overdoses go hand in hand. The reason is that they both are affected at the same level of ph. The lower the ph the more the cal/mag tappers off and becomes unavailable and vice versa the higher the ph the more these 2 elements become unavailable. Hope this helps
