Lock out? Nutrient Def? Plain stupidity?

Guys meet Grape Krush. She's 11 days into flower at time of pic. I moved her int her flower mix aprox. 3 weeks ago. 6 gal. pot/ bottom 3" - 2 prt peat/2 prt Permagreen Brand. Mushroom Compost/ 1 part play sand/1 prt perlite. Then 1" and fill dirt made up of, 2 part peat/ 1prt flwr soil mix(2prt EkoBrand Potting Mix/1prt Sand)/ 1 prt perlite./ 1 Tbls Bone meal for every 1.5sqft aprox.This prob in the pics in mainly on the Grape, and a lil bit on the "21". And seems to have fallowed the plant from veg but is now worst. I mist with a 1tbls apple cider vinegar to 4 part water solution at lights out because I was told it was Rust mold/ Black spot. But after doing this for aprox 5-7 days and looking around I think it could be lock out, K def maybe. During Veg I added extra N when I noticed the yellowing and such. Need more info ask, got any ideas as to what it fire away. This is my first indoor grow and only 2nd grow altogether so I'm lacking hands on knowledge

That looks like over fert to me........

Your feeding to much and to often...just use water for the next week or 2...until the yellowing gets better. Then feed her a little less and probably every 2 days or so.

This isn't nute burn in the technical sense, it's actually a ph problem. Although, improper and frequent application of nutrients will cause ph problems, the soil has dropped below the range of which it can absorb any nutrients, so your plant is actually starving. Give it a good flush with warm water and make sure its not sitting in the run-off. Make sure your water ph is balanced too.

You have a calcium deficiency due to acidic soil here you go

[FONT=&quot]Element Name:[/FONT][FONT=&quot] Calcium Symbol: Ca [/FONT]
[FONT=&quot]Atomic Number:[/FONT][FONT=&quot] 20 [/FONT]
[FONT=&quot]Atomic Mass:[/FONT][FONT=&quot] 40.078 [/FONT]
[FONT=&quot]Calcium is a soft grey alkaline earth metal, and is the fifth most abundant element by mass in the Earth's crust. Calcium is also the fifth most abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate.[1] [/FONT]
[FONT=&quot]Calcium is essential for living organisms, particularly in cell physiology, where movement of the calcium ion Ca2+ into and out of the cytoplasm functions as a signal for many cellular processes. As a major material used in mineralization of bones and shells, calcium is the most abundant metal by mass in many animals. [/FONT]
[FONT=&quot]Ca is an important Micro nutrient that marijuana plants require. A Calcium deficient plant (rare) is often shown by twisted or curled leaves and brown spots that can spread rapidly. Too much Ca can be lethal to your plant though. Potassium (K) and Magnesium (Mg) can be “locked out” if the Calcium levels are too high. Watch your tap water…”hard water” (tap water in most North American cities) is generally Calcium rich. If your faucet heads have mineral build up on them, your water is not recommended for marijuana growing…too many unknown minerals (usually a lot of Calcium) in the water. [/FONT]
[FONT=&quot]Calcium Deficiency[/FONT][FONT=&quot] [/FONT]
[FONT=&quot]When plants exhibit a Calcium deficiency the younger leaves are the first to show it as well as older leaves. The Leaf tips will die back, the tips may curl, and growth of the plant is stunted. The plant can show a weakness in the stems and branches, as well as a under developed root system that can lead to bacteria problems with roots dieing off. Having slow plant transpiration rates can aggravate the uptake of calcium. Make sure your soil isn’t very acidic, for calcium gets harder to be absorbed through acidic soils, Which leads to having a plant that is deficient in Calcium. The leaf tips, edges and new growth will or may turn a yellow/brown color that happen in spots and often surrounded by a sharp brown outlined edge and then the leaf tips die back. If too much calcium is given at an early stage of growth it can stunt the growth of your plants. Having to much of calcium will also flocculate when a concentrated form is combined with potassium. The parts affected by a calcium deficiency are the roots. Stem or petiole, young or old leaves. [/FONT]
[FONT=&quot]To fix a calcium deficiency you can treat by foliar feeding with one teaspoon of dolomite lime or Garden lime per quart of water, Or Any Chemical/Organic nutrients that have Calcium in them will fix a Calcium deficiency. (Only mixing at ½ strength when using chemical nutrients or it will cause nutrient burn!) Or you can take crushed up dolomite lime or garden lime in a gallon of water and water it in the soil. 1 to 2 teaspoons per gallon of water, which will be slow acting. Garden Gypsum, which is medium absorption. Limestone, which is medium absorption, Rock Phosphate and Animal wastes which are both medium/slow absorption. Note: Caution when using gypsum to an already acid soil (pH that is less than 5.5) can have a very bad effect on different types of plants by effecting the absorption of soil aluminum, which is poison to plant roots. [/FONT]

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. [/FONT]

I'll buy calc def or ph mainly because they only get water, I add no nutrients, all in the soil (I hope/think). I have relied on what is in the soil, using different mix for each stage of growth and using plain tap water. does this info change anything

Flush and supplement with epsom salts at 1 tsp/gal. Looks like cal/mag problem that could be caused by the low pH. The flush will get rid of any salt build up from feeding and preventing further damage by adding some epsoms. Good luck!

Ok let say I have 5gals pot that mean I have to flush it with 10gals of water. Do I do divided it into 4 times? 8 times? or 1 times ????

i would do 15 gallons depending on type of medium

Ok let me rephrase my question, Do I flush 10 or 15gals of water at 1 time or divided it into multiple time? Thank you.

I agree with this diagnosis. Some old over feeding in there, immobile element deficiency points to acidic pH.

I'd just use 2 gallons water to every gallon of soil. Aim for 6.6 to 7.0 in that. The problem isn't too severe yet.

I fixed the problem with the above advice in the veg room,BK and all of the clones look good. The flower room is a hard to say only because they are 20 days in and some of it could be N pull for the buds. However I have stoped my apple cider treatment (@ 1-tbls/1-gal) for the rust mold, which could be an on going battle right now. On top of things GrapeKrush doesn't like to be over watered so her yellowing down at the base and inner leaves could be from that. GRRRR, but all in all they look good. I need some 0-0-22 for them Blooming Ladies

Just to answer the Q.

i prefer to flush 1 gallon at a time. Then 5 gallons at a time.

So do 1 gallon. Give it a moment to flush through. Then another gallon.

Once you get 5 gallons through the media give it a break. Anywhere from 5 to 30 minutes is fine.

Then go back to one gallon at a time.

Keep doing this until several gallons of just perfectly clear water run through. It should come out as clean as it went in. And being that we are talking about dirt here... that might take a while.

From what I have read about Flushing you run twice the amount of water through the pot, ie.. 5gal pot=10 gal of water. Due it in one sitting but slowly enough that you don't over-flow the top of the pot or get the little rivers down the edge where the soil and container meet. Just what I've read, most people advise about flushing and such is geared toward Hydro it seems

"I mist with a 1tbls apple cider vinegar to 4 part water solution at lights out because I was told it was Rust mold/ Black spot"

You can give your plants mold if you spray with vinegar I had a room mate who used vinegar to shower with because he heard from his girlfriend it would get rid of his BO (it actually worked) but his bottle of vinegar that he left in the shower caused a huge mold problem, it was very apparent. The mold was only growing around the bottle of vinegar and inside of it like crazy freaky shit LOL! I would spray with some safer sulfur soap or leaf shine if you have mold. but I think your problem is burning from nutes or ph.

Yeah the apple cider wasn't working for me, and yes it is a soil issue that I think I have solved

i have the same exact problems on mine . how did you fix the problem ?? flush?

I flushed, let it dry alittle and then did epson salt. I have noticed it seems to be strain specific for me. All my girls are in the same basic mix yet only my GK is showing these signs which look a lot like N def due to a heavy bud production. But hell just cuz I read a lot doesn't mean I know a lot
