Cal/ Mag O.D. ???

[ElfoodStampo]

Real quick, Is it possible to give plants too much Cal/mag. I know there can be a deficiency but can you burn the plant with these as well?
Thanks.

 

[Jeffdogg]

You shouldnt even be giving them that much to wonder. If you feel the plants are lacking cal/mag give like half tsp or epsom salts per gallon

I gave them 60 ml for a 75 Litre reservoir. So, its less than is recommended, however I cut my nute regiment in half on everything in accordance with the mnfg. reccomendation. I saw a couple fan leaves starting to spot about 3 weeks ago, so I got some calimagic and added 30 ml. everything was good. Then last week I saw a leave with spots, but I cant tell if it was an older on or new deficiency, So,, I dumped in 60 ml this time...
What should be the ratio of CaMg to macro nutrients?

 

[Jeffdogg]

Yeah just cause your leaf has spots does not mean its cal/mag. Cutting the nutes in half as recommended? how old are they? If your cutting nutes then they are pretty young yes? Look under the leaves, by chance do you see little white nat looking bugs? Can you take pics of the leaves top and bottom?

actually yea I have a grow journal if u want to look at more but here's a pic.
I know i don't have mites, I had to go through a process of cutting back nutrients because I was burning the hell out of the plants using what the manufacturer recommended. AKA the advanced nutrients ph perfect line chart. I feed them 1/3rd of what they want me to, because if I do any more it DESTROYS them. leaves curl, brown tips, dots.. I think it's because of the immense amount of oxygen in the water. I don't think they need as much. The plants rifle though nutrients in like 3 days, and I have to add more. So I'm wondering what the ratio of cal/mag should be to the other nutrients, that way I can adjust the amounts depending on what else I'm throwing in there.

 

[Jeffdogg]

Yeah thats nice but pics in real light or natural light lol cant see the actual green leaf top and bottom like that and I mean close up pics like place the spotty leaf in your hand in normal light and take the pic then flip it over and take another pic, thx in advance ;P


Although i am having a hard time believing that system is yours.

In the pic on your finger write RIU.org in pen

Haha your judging a book by its cover my friend. That's not very respectful, however in light of the fraud that occurs on the internet I will entertain your request. I'll be right back.

 

[Jeffdogg]

Im just high and goofing with ya bro, really hence the " "
Stick around on the forums you will see how i am sry if you thought i was being disrespectful But i will need the pic of the leaf in hand on both sides to give some advice

 

[ElfoodStampo]

I used a permanent marker, so you got a piece of cardboard. There's one of my dogs. She's real. I'm real. I grow weed. I wish i did, but I do not resemble the handsome man in my profile pic.
Thanks for any advice you may have for me with regards to the cal/mag question.
Thanks.

Thats cool man, I won't lie I can be a dick.
But in a fun educational sort of way. or so I like to think.
I love everyone I think we just misunderstand each other a lot.
I really do appreciate everyone's help though, very much. It's nice to have help.

The leaves I pulled were the only ones I could find with the issue. Again, this problem was from at least a week ago.
I just now got RUI.org.. I was like what the fuck does he want me to write that for. Is it a porn site or something, fuck it whatever." haha I'm pretty high too. haha

Well lets check this out and see if you think one of these applies to your babies

Quick Deficiency Guide

NITROGEN (N) Pale plants, red stems, smaller growth. Rapid yellowing of lower leaves progressing up the plant. Add any chemical fertilizer containing N. Treated plants recover in about a week.

PHOSPHORUS (P) Slow or stunted growth, red stems. Smaller leaves that are dark green. Lower leaves yellow and die. Add chemical fertilizer containing P. Affected leaves will not show recovery but new growth will apear normal.

POTASSIUM (K) Affected plants are usually tallest and appear to be most vigorous. Necrotic spots form on lower leaves. Red stems. Leaves appear pale or yellow. Add chemical fertilizer containing K.

CALCIUM (Ca) Lack of calcium in the soil results in the soil becoming too acid. This leads to Mg or Fe deficiency or very slow stunted growth. Treat by foliar feeding with one teaspoon of dolomatic lime per quart of water until condition improves.

SULFER (S) Plants suffering from S definciencies exhibit yellowing of new growth. Mix one tablespoon of Epsom salts per gallon of water until condition improves.

MAGNESIUM (Mg) Lower leaves yellow and may even turn white while veins remain dark green. Blades die and curl upward.

IRON (Fe) Leaves on growing shoots turn pale and veins remain dark green. pH imbalances make iron insoluble. Foliar feed with chemical fertilizer containing Fe or rusty water.

MANGANESE (Mn) Necrotic and yellow spots form on top leaves. Mn deficiency occurs when large amounts of Mg are present in the soil. Foliar feed with any chemical fertilizer containing Mn.

BORON (B) Growing shoots turn grey or die. Growing shoots appear burnt. Treat with one teaspoon of Boric acid (sold as eyewash) per gallon of water.

MOLYBDENUM (Mb) Yellowing of middle leaves. Foliar feed with chemical fertilizer containing Mb.

ZINC (Zn) White areas form at leaf tips and between veins. Occurs in alkaline soils. Zn deficiency can be treated by burying galvanized nails in the soil. Chemical fertilizer containing Zn can also be used.

OVER FERTILIZATION Causes leaf tips to appear yellow or burnt. To correct soil should be flushed with three gallons of water per one gallon of soil.

Its cool bro we all have our moments, once again stick around and you will see me being a dick many of times lol..

I know which it is if it is one of those, but this is a learning experience

yea, I'm with you totally. give me a min.

 

[OldLuck]

leafs look like that when they have nutes splashed on them. do you spray your plants with nutes?

 

[ElfoodStampo]

ok Im going with
MANGANESE (Mn) Necrotic and yellow spots form on top leaves. Mn deficiency occurs when large amounts of Mg are present in the soil. Foliar feed with any chemical fertilizer containing Mn.

If I cut back on the amount of cal mag I'm putting in then that should correct it kinda naturally, Right?
Or Should I look for a fert with then Mn in it to supplement?

OR am I wrong......

No I have not, everything is in the can.

Man, Now I'm thinking its the Zinc.

 

[Jeffdogg]

Sounds good to me buddy, have you changed the solution in your rez to water?

 

[ElfoodStampo]

Great! Thank you Sir!
I don't understand what you mean by changing to water. I normally put my nutes in every Sunday with fresh water, and change it out every Sunday. during the middle of the week I add water, The plants go through 5 gallons every 2-3 days. When I add water I mix more nutrients in the same proportion I did at the beginning of the week to get the right ppm.

 

[Jeffdogg]

Ok you change it out, some systems can go the whole grow cycle without changing out the tank. They just add as needed

I meant just changing the tank out and just run it with water for a day or so so it will help leech out the excess mag in the plants.
