Coco troubles...

Hello, first a little back ground. I have a few grows under my belt now. I started with aero which was a mistake, then I moved to using coco coir. I really liked it at first, but I just haven't been able to get the results. My last batch was 2 plants that didn't fill out at all. It seemed like I had a P def. the entire grow. That was my 4th harvest in coco. I hit a patch and just lost 3 plants one that was 4 weeks into flower, and the latest 2 wilted and died on me before I could flip them. I will have to post pics later of the ones I have left. My 2 moms 1 is Wolverine Kush and the other I call Bitch plant. She is from bag seed and is really stuburn, she got sick and dropped 75% of her leaves and about half the plant died off. I was able to nurse her back to health and she seems to be doing well for past few months. Hence why I call her Bitch plant.

I use PBP Grow/Bloom Cal/Mag +, Super Thrive, Beneficial Biologics, and Hydroplex.

I use tap water in a 25 gal. res that I bubble PPM 125-150 after 24hrs of bubble.

I do a micro grow with 2-3 plants in flower using 1/2gal nursery pots.

Botanicare Coir also a 75% 25% mix with perlite and I add bone meal blood meal and worm casings when I mix my medium up. I let it cook from a week or 2 before I use it.

I keep running into the same issues with my plants. I have tried several different things from raising my PH lowering my PH, cutting nutes ppm adding ppm. flushing once a week, not flushing. Feeding every other day, giving a dry out time, feeding once a week. I just can't seem to get this figured out. The harvests I have had the buds didn't seem to have any bulk to them really airy, still good, just not what I want.

Now my issue.
The leaves on the top of the plants show what I think is P def. the darker green necrosis begining at the tips until it dies off. Some clawing action with Bi-folding down, and deformed leaves a that creates this damage toward the back of the fan leaves then they curl inwards back toward the plant. White necrosis spots on leaves about mid plant, not little one good size white spots then necrosis of that leaf. New growth on the top the serrations are deformed and bend upwards, and eventually cause the leaf to fold in half almost. I have tried continually feeding veg. at 5.5-5.8 and 5.8-6.0 ph for flower. I could throw in stunted growth also. And purpleing on the stems, but that could be from my temps dipping into the mid 50's - 60's when lights are off. and 70-80 when lights are on. I know I need to work on my temps but that's coming down the road, it's just really cold here right now. I just need some expert help. Am i growing in too small of pots, what am I not seeing or missing here. I can post pics later on tonight.

I did just start 2 more for flower in about a week or so. But I made 2 10L hempy buckets with straight perlite and about 1gal to be hold in the res drain hole 2 inches from the bottom. I am going to flower these in the buckets to see if there is a difference. Any advice welcomed. Please help. I am stumped.
 
I tried the botanicare coco crotons once and had really bad results with it. I rinsed the heck out of it and it seemed as if i coundn't get the salts out of it.

Try to use some of your coco without adding anything to the pre charged batch..I bet you will have no problems.
I only use mediums that have Organics mixed in. Im not fully into COCO I do a mix

This is my base mudium mix. I use allot of tea's with PBP bloom no grow..I mix these all together very well before use.
COCO

Perlite

I've tried plant coco with perlite, I just recently started adding in the extra organics. I was dealing with Cal. last spring and summer, thats when I added the organics. Fixed the Cal. def but still had all these other effects. I was reading in the infirmary about water. I do use tap water, but they mentioned sodium being a problem. Can I test for sodium in my water. I was thinking of making a DIY filter with zero water filters in a fill res to drain into my holding res. Also I hand water. Latest sched was feeding every 3 days. before that was once a week, before that was every other day.

you can make it what ever you want..The base is Alaskan living soil you can use any compost here that has good microbial life. I add Certified black strap and cane sugar's. I add high P bat guano for bud boosting. thats all. there tea mixes you can buy ready to use. just put it in a tea bag(some come with the bag) put it in your bucket and bubble..IMO tea's really help.

First, do a root exam for Root Aphids. Use a large low power magnifying glass, and you'll need to be quick because they retreat into the medium quickly. Also notice whether the roots are white like they should be. Are you inoculating with anything? Use a preparation like Great White or similar, or use a good Earth Worm Casting ACT. Roots Excelurator helps a lot. Good luck. -granger

when you lift the pot out have a drip pan ready. hold the plant above that drip pant and give the bottom a small crumble. put the plant back in the pot. Examine the dirt if you have RA you will see some in this soil thats fallen into the drip pan. From what you have said I dont think you have RA.Your problems started after you dosed yuor plants with the bloom boost correct? I think you over juiced her. It looks just like what im seeing on your plants. an you get any pictures that are closer to the damaged areas.

I'd work on dialing in those temps and RH, and make sure you pH pen is calibrated.
Good Luck. JR

Had Constant problems, not just with this grow. That's why I moved the latest batch to hempy buckets. Trying a new medium. I will post some pics tonight when I get home from work. They do really well in veg, some small issues. I can had heat to run on lights out if needed. I have a small space heater I can put on a timer when the lights go out. From what I have read about in the sick plant guide, It's some kind of nute lockout or PH problems. And I am confident it's not nute burn, I under feed them from the directions from PBP. I don't do 100% ratios. This is the start of my 3rd year Home-growing and I thought I had a good perpetual system going. But just can't get them to produce.

I am pretty sure you have broad mites. Symptoms fit perfectly and pictures confirm. You need to get a small microscope from Radio Shack (100X), or a similarly powerful loupe to see them. Actually it's easier to see the eggs, which you will find mostly under the leaf surface. Point is , they are microscopic, and can't be seen without a scope.
The other point I would make is: why are you mixing blood meal, bone meal, worm castings, etc. to coco? The only thing I would add to coco is a small amount of perlite if you must add something. Coco is a hydro medium and does not benefit from adding that other stuff.
You need to look at your plants from a microscopic level. Broad mite symptoms mimic potassium deficiencies. Check them out and report back. Radio shack microscope cost $10, or you can get similar one on Amazon for $10.
If they are broad or cyclamen mites, your battle has just begun. You will be in the fight of your life.
They are epidemic now, so not unusual to get them, especially if you obtained clones from dispensaries or other sources.
