Ok, two probs, one looks like cal, or potassium def., and the other looks like mold/fungus/rust, no white mildew tho.
HYDROPONICS/Aero Ponics

How much of each if using multiple?Hydrologic R/O water (by itself, its 5.5 ph bubbled, and 6.5 ph unbubbled), Advanced Connisseur@1020ppm wk1, 1/2tsp/gal cal-mag(130-150ppm), 1tsp/gal Advanced grandma eggy's Fulvic F-1, 2tsp/gal Botanicare sweet, 1 tsp/gal Botanicare silica blast, 2 tsp/gal Liquid Karma, 2tsp/gal hygrozyme, 1 tsp/gal Carboload(liquid), 2 tsp/gal hydroguard, hesi super vit@ 1 drop every 4.5litres, 1.5 tsp/gal gnatrol (the weather is warming and ive noticed 1 or two gnats around so i used this just in case they had any bright ideas), AND Plant Success Mychorizzae, trichoderma etc..@ 1/2oz/6gallons. Final unadjusted resevoir ph=5.5ph, and Final ADJUSTED res ph=6.0 (using gh ph drops tester, and hesi ph up), and 1680ppm's. I sprayed them with 3/4 strength organocide @wk3 veg, to try to control this problem which i strongly believe is some or various types of mold/fungus.
What is the TDS/EC/PPM you are using? stated above
What is the pH of the "Tank"? stated above
Are you sure your calibration is correct on your equiptment? yes
When was your last watering? every 2-4 days depending.
What is your water temps? 68 degrees
When was your last feeding change? veg gets sensi grow, and i just moved to flower, and switched over to Connisseur (ie. grow-bloom-micro-additional)
How often do you clean your system: example: Flush out water replace with clean water and nutrients? I flush every 2 to 3 weeks.

Has plant been recently pruned, cloned off of or pinched? light prune before onset of flower.
Have any pest chemicals been used? If so, What and When? Yes, A week ago i used x-clude 1600 pyrethum fogger as and aid in assisting my preventative measure of using gnatrol (gnatrol only kills larvae, not adults). Also, i was told that sum cuts i recieved came from a place with bad mites, but was assured that they were dunked in avid and placed and in area for a few days away from the infestation before they were given to me. But still, it gives me a piece of mind that i re-dunked them in avid a day before the fogger was applied. Before i put them into flower i also sprayed them with 1 part sm-90 to 5 parts water(un'phed).
Are plant's infected with pest's? I have 20/20 eyesight and can see everything and i say there is none. (plus i have a 30x microscope)

Ok heres some pics of what i think is a cal, or potassium def.










And heres the thing that i think is mold/fungus. It has showed itself in diff forms, thats why i think it could be various types.

















Ok, SO IF ANYONE CAN HELP ME MAKE MY PLANTS LOOK LIKE THIS AGAIN......


THEN PLEASE I BEG U, DONT BE SHY! THX

 

[DIGITALHIPPY]

its calcium, and phos OR ph flux. i hope your right about the phos, id say increase the nutes your using. LUI is a heav feeder.

 

[Core]

id say increase the nutes your using. LUI is a heav feeder.

i would say just the opposite...but thats just me...

 

[smurfin'herb]

why would u say opposite? im almost positive the first pics are calcium, but ive been giving my r/o 1/2tsp/gal cal-mag plus (=130-150ppm). So unless that doesnt seem like enough on top of whatever my connosseur has in it, then it must be a ph flux. My runoff (using 6.0ph r/o) is usually around 6.5 to 7.0 (im in coco) 3 days after i feed it. maybe thats why. One thing i dont understand with runoff is, for example: if use 6.0ph water and pour i thru the medium and the runoff is 6.5, then does that mean that before i watered, the medium was at 7.0ph, and is now is at 6.5? To clarify, if i add 6.0ph water to equal parts 7.0ph water, the result is 6.5. Im so confused when checking runoff.

 

[Core]

1600+ ppm's full feeding thats just crazy.....it could be doable in DWC or hydro...but not with coco, soil or soiless....if even hydro/dwc
but with what you stated now i more enclined to think you have a Ph problem on your hands...putting 6.0 in and geting 6.5 -7.0 in return means your ph is much to high for coco...you'd better drop the ph lvl a bity next time...lets say 5.4 -5.6....

 

[smurfin'herb]

the guy from advanced told me to start them on a feeding program which will have a 1600ppm peak! i told him i was in coco! right now they have 1020ppm connosseur, plus additives to equal a total of 1400-1600ppm. The Liquid karma adds a lot of ppms i guess, but i was told that u dont have to worry about it. So if i use the 1600peak feed program with connosseur, u think that is to much?

 

[Buzz Lightyear]

PPMs way too high

Adding sweet at that rate adds 42 ppm magnesium. Too much mag causes a calcium and/or potassium deficiency. Leave that out.

I am not sure of the value of the other accessory stuff your adding. Best to keep it simple.

[smurfin'herb]

they started it in veg, when they were only on 600ppms sensi grow A and B. So it cant be because of the ppms. Plus, last grow my ppm meter was on the wrong conversion factor so i was feeding way way more (1800-2000 ppms of just connie@peak) than now and they still came out awesome.

The leaves just fall off after it takes over, thats why i think its mold In the bottom pics. A deficiency/toxicity doesnt make leaves drop from the plant does it? Stitch could i get your opinion....?

That's a great feeding plan they offer that will have you @ 3.0 to 4.0 EC depending on how you calculate. I say fuck that, take a syringe and inject the concentrate into the plant, you'll get a pound per watt easy!

Plants in coco react pretty quickly to changes in feeding. Back off the nutrients to about EC 1.5 ( x 700 or 500 for ppm depending on the conversion of your meter) and drop some of the additives. Then get your pH inline and look for signs of recovery within a few days. If they look starved, then increase your feeding with a basic mix of calmag, connoisseur, LK and hydroguard/hygrozyme. I would also do a flush (lots of water) because there must be incredible salt build up since you water only every 2-4 days and those pots don't look that large. This could also be the cause of your pH problems. Drying coco quickly builds up salt toxicity.

 

[easyrasta]

It looks like too much nutes to me. especially on the 1st, 2nd 4th & fifth, eighth ninth and tenth pics.
Third pic looks like mite or white fly damage which is possible in coco.
6th and 7th pic looks like you split something on them and the light made the water marks.

By salt toxcitity do you mean that as the water is used, the ppms become more concentrated? and if this is what u are saying, then wont a simple watering fix that? if its not true, then please explain what u mean, and why i need to flush if the coco dries out.. thx!

 

[wygram]

Yes, you're on the right track, But the extreme environment created by salt residues even when they are re-hydrated is too much for roots to function properly. You need to wash the salts out for the root cells to resume uptake of water and then later nutrients.

I'm not the only one saying it, look up. "It looks like too much nutes to me." and "PPMs way too high" Your leaves are dark dark green and clawing with burnt edges. Those are signs of lockout due to overfert.

How big are your containers? For 3-5 gallons or so you can water every 2-3 days, smaller containers require more. Coco is a semi-hydro medium, it can be very wet and still hold a lot of air.

 

[smurfin'herb]

Thanks for clearing that one up for me! So how do i keep my ph more stable? it goes from 6.0 feed to 6.5-7.0 runoff after two or three days! Any good way to avoid this?

 

[easyrasta]

You want to drop your ph to about 5.9 at first.
Allow it to swing up to 6.4 and no higher.
Different nutes are absorded between the low and the high.
Good luck

 

[MynameStitch]

Those plants have too high PPM count.... would reduce the ppm count if I were you.....

 

[smurfin'herb]

ok thanks stitch. so what would u recommend i take ppm's to for the 2nd feeding of flower? should i keep a constant ppm number for all feeding throughout the cycle, or start of small, then work it up, then work it down towards the last weeks? thx!

 

[smurfin'herb]

anyone...?

 

[MynameStitch]

You should always start out small and work your way up.

You will know when they need food by when you check your ppms and if the ppms go down more quickly than normally you will need to up it.

Like you sould always keep a steady ppm, but if it keeps going down a lot more often then normally you top it off then it's time to up the dosage a bit...

Would not go over 200 ppm at a time when you increase your dosage.......
For the size plants you have I would not go over 800 no less than 500ppms......since they are being burned.....
you have it 1600 which is very high, that amount should be to about 4 to 5 feet tall plants.....

 

[smurfin'herb]

thx for answerin stitch! so once i hit 800ppm, ur sayin i should keep it there until flush..?

 

[MynameStitch]

Keep it there until the plants need more food, but since you are in veg still, the plants will hit there spurt and eventually in flowering you will need to up the dosage.

If 800 still seems to be burning them, drop it to about 600 for about a few days then slowly up it back to 800.

When plants get burned, there tolerance to nutes goes down slightly until they fully recover, then they eat like mad once they get there root zones fixed up

High nutes burns the roots which in turn you see it on the plant.....
