Growing in Coco 10 years. Lost my way - Cannabis Infirmary - International Cannagraphic Magazine Forums

Hey, I'm just about at breaking point with my issue. So really help some pros can help me out. Is hard to even ask for help but I'm fed up now.

I hate posting here and I'm a stubborn fool but I can't figure this issue out. I've got that stubborn don't need help shit going on but I give up now.

OK.. Long time Coco grower.. 10 years ish.
Always used advanced nutes. Sensi bloom.
Plants in veg are epic. No problem.

Get them into flower,
2ml a + b sensi bloom litre and 2ml per litre bigbud bud. That's it. This was golden for years. Never changed a thing used to water with no run off and prob water 1 or two times a day. No issues.
Only tap water that sits at 100-200ppm.

OK so around autumn 2016 I started getting Nitrogen toxicity. The clawing and deep green leaves. That grow and the next I backed the feed right down to 400ppm just to get them through. But of course the low feeding just fucked them up more.
This went on for 4 runs. Pretty much yield dropped off about 35% maybe more.

So fast forward to now. Switched to the Coco version as it's lower in Nitrogen. Then feed at
1.6 ml per litre a (*the Nitrogen is in the a)
and 2ml per litre b.
2ml per litre bigbud.
0.5ml per litre cal mag
PH 5.8/5.9
Total ppm 400/500 ppm (x500 scale) so ec is
0.8 to 1.
Roots: pearly white and thick root mass. The roots are perfect.
Watering with slight run off now.

Just tested the run off of one plant with the clawing and ph was ph 5.4 and the ec has doubled so coming out the bottom of the pot at 700/800 ppm.
And still getting the Nutrient burn/Nitrogen toxicity.
2nd week in flower. I know it's gonna fuck up my yield again when I can't afford to have another shit run. The finished bud is good but obviously could be better.
Oh using canna professional Coco in 6.5 litre pots. Plants are like 3ft tall and bushy.

I did even switch to the canna coco a +b for a run at 2ml per litre and had the same problem and my heart just sank. Idk what to do anymore.

So feeding at 400/500ppm
Sensi bloom a + b = 1.6ml A, 2ml B per litre
Big bud right now 2ml per litre
Cal mag 0.5ml per litre
Canna coco bagged
6.5 litre pots
Watering till run off one or two times daily..

Ppm in 400/500
Ppm runoff 700/800

Ph in 5.8/5.9
Ph runoff 5.4.
Plant heath apart from the toxicity is great. Thick stems etc. Perfect roots. New growth (leaves) n toxic and dark green and clawing.

Htf can you get clawing and toxicity at 400ppm??
Why is it doubling in the run off.
runoff collected after feeding the regular feed BTW.
Crazy. Ph is on point. Root mass is on point. Runoff check. PH check. Ppm check. Room temp 26c/78.8f lights on 20c/68f lights off check. Air movement great check. No bugs at all check. Lighting good check. Change of location half way in between these issues check but same shit continues check. :-(

Maybe your municipal tap water changed sources throwing your nutrient profile? Maybe up feedings to keep salts from building to 7-800 ppm. Not experienced enough to really help but this is what i would try. Good luck.

siftedunity · 01-16-2018, 06:28 AM

I have thought that the water my have changed sources.
But cannot confirm that.
And yes I could up feedings but any more runoff and they will be too wet all day and night. Thank you for your input though my friend

Tap water is constantly changing, lots of reasons

Change to Canna nutes

I used Plant Magic for years and had issues similar to you, swapping nutes seems to have solved it

its probably the water ,,i been having same issues but mag deficency, 2nd week into flower and not able to correct it ,,yield have gone down crazily ,,,pulled me hair out ,blamed everything ,changed everything ,last resort blame the water ,it reeks of chlorine ,the tap water has to many bicarbs and sodium in it ,this causes lots of lockups ,tried using calmag but made it worse ,,tried flushing made it worse , so i mixed half brita filtered and half bottled spring ,,its solved the issue for me

Thank you for your input. Much appreciated. Can change to canna but why will that solve the issue? I will try it if it works out

Man I feel your pain.. Sorry to hear about you issues but I'm glad to feel it isn't just me. Problem is by about 4 or 5 weeks in they just seem to get on with it and Finnish. But by that time the damage is done. In the case of nitrogen toxicity the plants stretch but the stem in between doesn't fill up with bud tissue. So it kills the yield. I even had calcium deficiency too at the start. Hence why I added the calcium at 0.5 ml per litre. That was solved. Then back again to the n toxicity. Tbh I took for granted how I used to be able to run a line of nutrients with no issues. Seriously considering to switch to Ro water. Its the only thing I've not changed is the water..

i changed from canna to house and garden to vita to bcuzz to ionic back to vita,,don't matter what i used same thing happened :(

I too lean towards your source water as the issue. Try a 50/50 tap/ro perhaps?

Up here the water is very clean but with soil erosion, turbidity (large particles carried by water force, not dissolved solids) increases and you can smell the chlorine when it rains. Arbitrary turbidity caps (in other areas up to 5 NTU, here 1 NTU) mean lots of chlorine and frequent boil water advisories.

Poorly filtered well water abounds, bringing a range of issues.
