PK from SR-71 in Coco w/ House and Garden Coco Nutes.

Totally Recovered!!

Totally Recovered!!

So,... I rinsed the coco with 3x the container size of water that had been pH adjusted and did the weekly nutrient change-out without increasing the concentration and... all the curling leaves straightened out and the have the lovely green color back!! Pics will be posted tomorrow showing the improvement. The light has gone off for the day.

pH: 5.9
EC: 1.3
week 2 of flowering

Runoff

Runoff

So the runoff is now 0.1 ec gradation above the nutrient solution they are being fed with, also with a higher pH. It has only been three days since the coco was flushed, I am wondering if maybe a daily flush should be incorporated into their daily regimen? Any ideas?

Hey there Viktor. Nice going so far. im digging this grow.

I've used botanicare and was very happy with it. Right now i'm running 21 plants in B'cuzz. It is a lot finer then other coco I have felt. Next time ill be switching back to botanicare becuase I heard somewhere here that it has less salts then other brands and it was alot more coarse.

As for adding a flushing to a daily watering regiment might be too much for the plants. I would say Flush once every month just to be safe. Maybe it would probably be best to just reduce the amount of nutes your giving them...just an idea. Looking great though!

EC is a little high. Their EC should remain either stable or go down slightly over the course of a week. pH should always be stable regardless.

Are you sure you are adding the right amount of down such that pH won't shift within 24 hours when just sitting, not being used for plants? Would you happen to be bubbling their res pretty vigorously? Too much aeration in the res will result in phosphoric acid being bubbled out, i get the same problem when the mixing pump output gets too high above water level.

With all of those things in check a flush every 7-10 days should be sufficient.

My favorite coco right now is Botanicare's, B'cuzz was too fine, sunleaves chunks are excellent for drip, but take too long to flush. It's not good enough merely to rinse chunks, they must be soaked 24 hours, then drained, then soaked again ad infinitum. It's not so much a matter of chunks not holding as much water, but that they take longer to do so, and why they are great for drip, but need to be soaked first as stated. Botanicare, at least the batch I got had many more of the long, uncut fibers, maybe a ratio of 2:1 long:short vs. B'cuzz which is more like the reverse at 1:2 or even 1:3, just judging by eye and how the meduim changes over time. Hydro store employees (insert grain of salt) told me that B'cuzz is already 'charged' with nutes, well rinsed and prebuffered....such that you only need to add pH adjusted water the 1st week or so. My experience was that they were exactly that. Maybe your batch was bad?

I've tried HG nutes, and didn't really like the results. I got funny yellowing on all the leaves, not an N def, but looked like a sulfur def or something weird. Canna and Advanced have both done me right though.

As far as the coco goes, I always just ran my drippers with a full rez of RO water off and on for 24 hrs, then drained and refilled the rez. No probs.

Look forward to seeing your results with HG though, and hope you figure out the prob if it's still around.

So they have been in the coco for 11 days and in addition to the A&B nute schedule the H&G root stimulator is being used. In those 11 days a 5% neem solution was added every two days for bugs and PM. The clones are planted in 2 gallon mesh bottom plastic pots and as of their move into the flowering chamber all but the smallest clones' roots were already growing out the bottom.

Hi

Nice grow keep up the good work

What do you mean a 5 percent neem solution was added? for what bugs are you talking about, cause i have a fungus nat prob and i cant stop them from breeding. Did you add the neem oil to the medium?

Thankyou in advance

EDIT: also your ec is to high, i was getting leaf curling and defs cause i was using high ec like you, the ph in the medium will drop due to excess nutes not being used, so flush with ph'd water until the ph returns to 5.8 - 5.9, and then everyday monitor the ec and ph, ec should drop slighly over the week and ph should rise slightly or remain the same as the nutes gets used up over the week, if the ph drops that means your ec is to high.

Lets See...

Lets See...

So, I concur with everyone, the EC is too high. I guess these PK like a lower concentration of nutrients. The neem oil I applied as a spray of 5% solution with just a drop pf liquid detergent to help the oil emulsify. A insect problem never developed and no PM so far. The area that the plants were vegged in is an outside porch area so, all sorts of bugs come to the water and the light. It's my understanding that neem oil is beneficial in that it helps the plant develop its own bug and insect defenses. Once moved indoors to flower a sulfur burner is used weekly as a preventative against these same threats.
Hope this helps!

Nutrient Concentration

Nutrient Concentration

So it appears as if this strain (Purple Kush) is nutrient sensitive. This is the second week of flowering and the solution is at 1.1 EC going in and 1.4 EC coming out. I guess the feed solution concentration will be coming down again upon switchout. Has this been anyone else's experience with this strain?
Thanks,
Vik

I am running the full House and Garden line on 12 lights with coco/perlite and am loving the results. no nutrient difficiencies or overdoses and running exactly what the feed chart says for each week. Never adjust the pH. Couldn't be happier.

 

[clowntown]

Never adjust the pH? You never check/adjust the pH of your solution? Or you have no need to set/adjust the pH more than once since you're draining to waste?

 

[ViktorVaughn]

I asked the same within pico's thread. Either I am way over complicating this or some people just get really lucky. I'll only know for sure by doing it myself I guess!

 

[meduser180056]

ViktorVaughn- What's your PH?

The word out of SR-71 is to max out around 1.2 EC when running PK in coco.

pH

pH

Well my pH truncheon isn't working again(!) so I am using the general hydro drops. I am color blind so give it whatever error you want but I believe that it is around 5.7, 5.8. The nutrient schedule I received with the House & Garden started at 1.2 EC so this explains a lot. Thanks Meduser!
Vik

 

[meduser180056]

Yah it was either 1.2 or 1.4 I don't remember exactly, but still that's during peak flowering in coco I remember them saying. I remember being surprised cuz it was so low.

 

[ViktorVaughn]

Nutrients Changed

Nutrients Changed

So did this weeks nutrients change out and this week the schedule called for BudXL. I added that after an initial EC of 1.0. The runoff this morning was measured at 1.4 but my first watering is now going to 50% runoff. My plan is to have this weaker nutrient solution self-flush this week to see if we can attain the ideal nutrient concentration where the runoff matches the solution going in.
Anyway, pics follow!

Purple

Purple

So, I was wondering about getting this strain to turn purple. Do I need to drop the temp at some point? And if so when? I already turned the AC up a bit so its averaging 75 when the light is on and 65 when the light is off. If anyone knows I would greatly appreciate it.
thanks,
Vik

 

[meduser180056]

Get some Purple Maxx and start soaking those girl with foliar feedings of it. Don't use more than 2 ml/gal when foliaring with Pmaxx.

Watch out for mold. Get plenty of air circulation going if your gonna foliar. Do it an hour before lights come on.

Also let them go at least 8 weeks.

 

[ViktorVaughn]

Thanks

Thanks

Thanks again Meduser. It sounds like this is a cannabis selective product, so they should have it at the growshop?

 

[Brain]

I'd pass on spraying budding plants with anything. Plus, your temps are fine for bringing in the purple. This is the first I've heard of applying purple maxx as a foliar. I know people like the purple but lets get real. Spraying your buds to get them to purple is straight up retarded. VV- Your temps are great. If you wanna make sure you get maximum purple you could drop the night temp another 5 degrees. My PK, also from SR71, purpled up completely with night temps in the low 70's. Just keep'em healthy and they'll start doing what they do around day 40.
