Im sure i have more than one thing going on here... so im loking for advice.

1.2m x 1.2m tent
Strain: Aurora Indica Feminised - Nirvane
Veg: Not sure exactly but i would say longer than 8 weeks
Switched to 12/12 about 4 weeks ago
PH fluctuates but i have never measured it higher than 6.2 and never lower than 5.6
Growing in Cocco (100%)
Canna Cocco A&B Nutes
30 liter pot
32 liter reservoir
Temps dont go above 27C and dont go below 22C as they are controlled
I have a dehumidifier in the tent
I have no light leaks
20cm oscillating fan - always on
120mm PC fan extracting air
Occasonal use of Superthrive

Problems i have had that arent in the photo: Algae in the reservoir, Tiny little white pests crawling through the cocco about an inch below the surface - too small to take a photo but just big enough to see when they move.

Things i have done:
Foliar spray with pesticide - NO EFFECT
Used Neem Oil in reservoir - 1ml per 5 litres (as per instructions on the box)
Sticky Strips - Caught absolutley NOTHING!
Hydrogen Peroxide in the reservoir - this cleaned the reservoir and im not sure if this had any great affect, but it might have helped a little.

I still have problems with algae. But im worried that the more i keep adding the peroxide to my reservoir does it affect the ec and ph??

I have nugs forming and the plant is starting to smell nice. But the foliage is starting to look poorly and growth is stunted.

The worst damage is at the top of the plant and most of the leaves near the bottom appear healthy but there are some that are showing signs.

Here are the pics any advice given is advice well received. Any questions feel free.

NOTE: These were some of the worst leaves i picked off.

suggestion?....

vtmi'kmaq - what are you saying with that pic? do i have burn or def.... because i cant make it out when i compare the photo's...
 
well lest try this then, from now on when you water add epsom salts to plain water, see if they go away , i honestly have no clue whats going on specificly but i do know how to help the plant recover from most ailments. Shit i just realized your in hydro, imho next grow switch to soils, preferably organic -notillsoils, much less of this!
 
Imo actually the leaves look like u have a nitro def from the dark green color, plus get a magnifying glass because it looks like u have spider mites!! Good luck bro!!
 
The third pic was from the very top....

I thought n def starts on the lower leaves.

I was going to flush her with h2o2, do you think that would help?

Also, i thought i might have mites about two weeks ago but i havent seen anything on the leaves.

Only evidence of bugs is in the cocco... So i thought flushing with h2o2 might help.

I also think i have a lockout but not sure what or why.
 
Okay. I beleive the ph at the roots is cloer to 6-6.2 as my run off tends to creep to that level and then it stops..... But i had been ph'ing the nute solution to about 5.7. So i will take your advice and try and raise it to 6.2... Thanks.
 
It sounds to me like the canna stuff is pre buffered. With that note I think you're over doing the nitrogen. So use less veg nutrients and make sure you adjust that ph. It might change because you use less of that product.
 
Add frozen water bottles to the res once or twice a day to keep the water cooler, it will help keep the algae down and the plant likes the cooler water.
In Hydro I was told and had success keeping the PH @ 5.8

U cant see spider mites with the naked eye u need a magnifying glass, also if u see webs in the plant she has mites 4 sure. Good luck!!!
 
Happy to advise that the bugs in my cocco are dead/dying and i am seeing evidence of dead/dying fungus/algae or both. Reservoir is clear and i can see new growth which doesn't appear to be affected.

What have i done: a slightly stronger mix of h2o2 flush with no nutes for the days since flushing and i am trying to stabilise my ph closer to 6.2.

It appears that the h2o2 is good at alot of things.... Yay!
