Everything has gone to hell since my last post. Please help.

Since my last post, 2 weeks ago, my plants have got worse, about 75 percent of the leaves are effected and pretty much all the larger sun leaves look bad. I don't know what to do anymore, hopefully some experts can take a look. The plants are 3 1/2 weeks into flowering, can they be saved at this point?

Platinum cookies, growing in 3 gallon pots in Cyco coco with perlite using General Hydroponics nutrients (and feeding according to their Flora Series, Expert Drain to Waste feeding schedule), I aerate my water about 24hrs in advance and usually feed around 700ppm at 5.8 PH (I ramped up the ppm some since the last post due to the suggestions from forum members). Early in the grow had a calmag prob, which I started adding calmag to each feeding, seemed like that deficiency was corrected, after that seemed like a Manganese deficiency, added "Bushdoctor Boomerang Comeback Formula," off the suggestion of my local hdyro store clerk (that was 1 week ago). With the problem still going on, I added "Great White," off the suggestion of another hydro store clerk to correct "the problem." No one has been able to accurately define the problem, I flushed each plant with 6 gallons of 5.8 PH'd water last night. So for the next feeding what should I do? Can anything even be done at this point? I'm seeing so many leaves curling up and dying and the ones that aren't dead just look so bad. Is it just time to scrap this grow and move on or do I still have some hope?

PLEASE HELP..

Not sure if you can save them. But, go by some dynagro and use that. Ditch all that bullshit your hydro dealers are telling you.

Then on your next grow, switch to soil and stick with some basic nutrients like jacks classic.

Stay away from hydro dealers, most dont know what they're talking about and even if they do they care more about making money. Obviously there are some exceptions, but from your post the people you are talking to are not the exception to this rule.

are you using distilled or r/o water?

Looks like potassium deficency to me possibly compounded by phosphorous deficency.

Whats your mix in ml/gal?. I use flora and never see this.

I use Tap water that comes in at 8.2 PH. I fill a 32 gallon plastic trash can and aerate it for at least 24hrs before I add my nutes. I add Cal/mag first, then Flora Micro before adding the other nutes on the schedule (as I was told those two should go in that order first so it absorbs into the water better). After all that, I add PH down until I'm at 5.8 PH before I feed.

I would tell you if the ph is in check soil between 6 to 7 and hydro 5ish. then ph is not the problem . im seeing some really red stems . usually a ph problem . my advice is to throw that nutrient brand into the trash , hit them with some veg solution, yellow leafs , the n is very low . advanced nutrients is great. or even hate to say it miracle grow some people get great results, idk if your in hydro if your ph is over 5 it could lock up the plant wont absorb the nutrients .

In hydro ph needs to be centered at 5.8.

Since you have flushed there aint much left but to feed it.
I think some grow wouldnt hurt aslo as it appears to be eating itself to death.

Stop using tap water. My bet is your ph looks good but it rises after you use nutes.

Try lucas 0/8/16 sans calmag.

I'm gonna go with nute lockout from ph flux also,for the win alex.

I always read "micro" first, but I dont know that that couldve cause your problems. Honestly it looks like you just have a sensitive strain,the purpling is normal from what Ive seen of platinum cookies but that bleaching and necrosis of the leaves looks like it couldve been done by the flushing of water through it. If the leaves were already deficient of something,getting all the nutrients leached out and sitting in water logged medium is enough to mess up a finicky strain. Sorry, better luck next time.

You don't need to add cal mag with tap water.

Is RO water a must? Logistically I can't do that right now for the amount of water I'm using. Is there another option?

If it's a lockout and I've flushed, for my next feeding should I feed at regular strength or less? Also, can adding Great White and Humic Acid help or should I just wait and stick with the GH 3 part since the plant seems beat up? I'm just not sure how much more stress it can take and if adding to many things will make it worse..

I wouldn't give it anything but p.h.ed water until it bounces back a little. You don't have to use r/o water, but filtered water probably wouldn't hurt.

Yes...the other option is what you're doing. Obviously something is drastically amiss and I'm with Chuck Estevez that you;re suffering a lockout. With so many different deficiency symptoms, it almost has to be.

Here's a link to an experienced coco growers suggestions regarding coco and Lucas formula. Very pithy and to the point. Scroll about 3/4 down...

And lower your ppms.

Be sure to water to 20% runoff or more every time. Good luck...

Btw thanks for the help/suggestions everyone.

What would you suggest I should I lower my ppms to ?

Ok bud, get ready for some hard truths. first i will start out by saying you dont have to scrap your shit, but its not gonna turn out the way you want. 2. any legit cookie strain is hard as fuck to grow unless some1 had a cut for a couple years and put it through hell, then it makes it easier on "any" grower to grow.But if its just a random cookie clone or from seed or whatever, your in for some fuckin shit. there nitrogen sensistive and potassium and phosphorus whores. you have all kinds of nutrient lock out and deficiencies from flushing with tap water. whether its ph'd or not. Dude, if your gonna run synthetics, and you dont want shit like this to happen, you need R.O water or distilled water. you can get the gallon jugs for a dollar at the store, or a 5gallon jug is like 7 bucks and 1.50 to refill everytime at those big ass machines. u just need to look for the ones that say processed by reverse osmosis, carbon filtration and treated with UV light. You need hygrozyme or sensizyme and flush it with r.o water, but not gallons worth. dont drench your plant. if its a 3 gallon, put one gallon of r.o water with hygrozyme in it. do that once on "friday" and then again on "sunday" then you need to start feeding her potassium and phosphorus at half strength and nitrogen at 1/4 strength. the nitrogen will only be for one or 2 feedings. Make sure you incorporate the great white into every single watering at 1/4 strength. that means every watering not every feeding. You need to get vitamin B and you need to get nitrozyme or some other kind of seaweed extract. I would use the vitamin b at full strength and the nitrozyme at 1/4 strength. Your plants have been cannibilizing everything because of nutrient lock out, and being flushed with tap water. even if its aerated and shit, it has chlromine and chlroamide and various salts n shit in it still that will fuck your shit up when used at massive levels. To diagnose a plant you must see where the problem is occuring, when it happend, what you were doing at the time, in order to figure out how to fix it. When you see leaves are dead towards the bottom but everything is kickin ass uptop.. and the leaves look like they have been stripped from the inside out, then the plant is cannibilizing itself for nutrients. When you see burn spots in the middle of the leaves its due to some type of toxicity but since the color is being stripped from there as well, we know that its phosphorus defecient along with being burnd with magnesium or calcium from the hard water. So, enzyme it a couple times with only a gallon maybe a gallon and half of water. thats 15 ml per gallon with hygrozyme. you can use the great white with it because it will help the roots intake other shit the plant needs. After all of that, just follow what i said above... vitamin b.. nitrozime/seaweed extract.. 1/2 strength phosphorus..1/2 strength potassium.. 1/4 strength nitrogen..1/4 great white do all of like.... monday do all of the above... wed/thurs do all of the above.. sat/ sun only water with r.o water and enzymes and microbes.. thats it.. then repeat above for another week. after that week is up you shuold be able to increase dosages except the nitrogen. and you continue to "feed....feed....flush" this is a cannabis award winning cup method. any questions just let me know. and humic acid is always good. either small dosages through out, or large dosages once a week or once every 2 weeks.

FP,
There's definitely some burnt looking leaf tips and plant is rather dispirited. I'd chop the ppms iway backfor a week (half or less) and start easing up again after that. You also might back the lighting off during that week also. Treat it as if it's just a nutrient burn...which is at least part of the picture.

I don't have a thousand posts. But can tell you that you will not get out of the hole those girls are in. I agree with the post with going to soil. I have never seen plants in such bad shape. Fixing the nute locks will be expensive.
