MangoXUnknown nute def

[Guest]

My Fourth Grow, a staple sativa x indica x rudy cross from a friend. Tough as nails and stinky as stank can be but average yields. Seeds from a Mango cross unkown to me (yet) birthed the front middle gal. Not as fruity, cat pissy as her sibling was before I made the unfortunate error of poisoning her with some bad judgement, but a skunky soon to be kola yielding mama!

They all are dining on Jack's Classic + micros (included) and some Knock out Gnats at regular strength (those wankers, curses Home Depot, CURSES!!).
The MangoX is showing yellowing fans like a N def.

They are all at about 3wks 12/12.

Magnesium deficiency. Jack's classic contains very little mag. (and no calcium or sulfur). Drench with 1 teaspoon epsom salts per gallon of water. Only do this once. This leaves you with calcium to worry about. Add 1/4 teaspoon epsom salts + powdered gypsum (calcium source) per gallon of water along with the Jacks. Do this everytime if no dolomite lime or levels are low. Do this every 3rd fert if dol. lime and just to keep levels good.

<tokes> also.....FYI

They are under 400w HPS

The Jack's Classic Blossom Booster is 10-30-20

At the first sign of yellowing, I began Neptunes Harvest Fish & Seaweed 2-3-1 at 1-1/2 tsp per gallon
but my feeling is I should be adding just the Fish 5-1-1 instead.

I also have been foliar feeding lightly with Shultz liquid 10-15-10 at a mild 4 drops per qt (versus 7). The corrective actions began about a week and a half ago.

(See also above my slow poke torpark post)

Here is a great opportunity to ask a question that I have been meaning to do so for some time, about mixing things.

"drench with 1 tsp epsom..." Wait till she is dried out and ready for water and do so seperately, or do I incorporate this with the regular nute feeding (ie mix all together in the same gallon with the other nutes)?

And to confirm, the same question applied to your succesive treatment of the 1/4tsp epsom and gypsum, Mix all together with the Jack's?

MMM, thinks about sipping beer and runs to fridge awaiting the answer.

MMMMM Homebrew.

 

[sproutco]

Drench with the 1 teaspoon now even if wet. You want results fast right?

Yes, add gypsum and epsom along with the Jack's as needed. Together.

Now, time for that j

 

[Guest]

Nice! <Runs to Cabinet with Homebrew in hand> (No, the running with scissors rule dosn't come into play here)

Also, anyone else using torpark or am I just being way paranoid?

 

[sproutco]

I have a spray rate if you need overnight results.

<Reads above post after returning due to neglecting to write down sproutcos instructions>
Of course i'm interested!

 

[sproutco]

Since its mild you can use 1/2 rate. 1 1/2 teaspoons per quart/liter of water. Spray both sides of the leaves. If you intend on eating the leaves in brownies, for example, wash the plant at harvest in the shower. Epsom salts is a laxative.

 

[Guest]

Finishes joint. Confused. is that one and one half tsp per quart for the spray? The orignal quote for the gallon drench you said was one half tsp per gallon (which seems even milder)

 

[sproutco]

Spray is alot more concentrated than what is exposed to the roots. Leaves don't do so good with absorbing nutrients like a root would. The spray rate is about 1/2 strength. Full strength is about 4 teaspoons per quart/liter. I got this from Howard Resh. http://www.howardresh.com/ Definately an expert. Look for his books at the public library. Either drench or spray but not both.

Time to smoke the other half of the joint. Isn't it fun when you know exactly what's wrong?

Edit: curative rate for drench was 1 teaspoon not a 1/2 teaspoon like your stating. Actually...smokes a little of the joint...curative drench rate is 2 teaspoons per gallon but your condition is mild so i thought 1/2 rate...

If you spray, aim at both sides of the leaves. Don't spray a hot bulb or it will shatter. Turn off lamps and allow to cool first. Its all about safety.

 

[sproutco]

Well, what did you decide to do?

 

[Guest]

Went with the drench as my sprayer is full for my veg and my other is clogged.

I gave the perscribed amount of 1 tsp per gallon and used a full gallon like a flush on the rather small pot she is in (roughly 8"). I will now wait till she dries out before resuming the second perscribed feed.

Any comments on my rather tight confines in the cab? I have tried to be more liberal this grow with removing suckers even though its hard when they are all haired up.

 

[sproutco]

Keep us updated about what happens.

Well here we were Pre-treatment:

 

[sproutco]

Once a mg deficiency occurs, it is very difficult to correct, particularly if the deficiency occurs in the mid point in the growing season. In those plant species that have a high mg requirement, the deficiency may be triggered by various environmental and physiological stress...An interesting side effect of mg deficiency is the possible increase in susceptibility to fungus disease.

Flowering is stressful and can trigger the deficiency.

In his last pic, the solo leaf pic, it looks like the viens are yellowing out first instead of the intervienal areas. Is that normal in mag def? what about the leaves dying from the tips?

UPDATE

UPDATE

Ok, so the 1tsp per gallon/epsom was administered on 1-4-07, 4 days later, she is definitely starting to green back up. Of course some of the leaves that were far along dropped but I planned on trimming some anyway. Last night she was dried out so I commenced sproutco's follow on advice of 1/4 tsp per gallon epsom/gysum along with the jacks and now I have some Questions.

First off: I am following the directions on the Jacks for "indoor plants" which calls for only 1/4 tsp per gallon with every watering (now avg at least once a week).
1) is this too little?

2) Sproutco, your follow on of 1/4 tsp/gal epsom and gypsum, is that 1/4 of each per gallon?

3) I'm using Garden Gypsum, which does not seem to fully dissolve in water. Normal?

4) Lastly, Y'all take a look and you'll see my cab is a little tight. I have slowly been trying to change this which each grow but its a tough habit to break.
The ladies are at about 4wks, Is it prudent to trim many of the solitary fan leaves to allow light penetration? (leaving only leaves adjacent bud sites?)

Please critique me into a higher yield!!

(ps I'll get more photos up soon!)
