Can someone help out with these - Coco

[Smokes1809]

Hey can anyone help me out with these, they lacking that
Green luster, and can't tell weather they overfed or underfed
Some lower leaves tips point up, none down, tips roll up
couple of dead tips at the bottom on the ones that curl up,
Leaves are dark, but I don't think it's n tox, as no tips point down
No clawing, no burned tips not at tops of the plants anyway
Few margins point up to, mostly margin rolling, roots underdeveloped
Look like heat stress but can't be, Lamps 2 ft above them..


Canna coco, canna coco a and b and perlite
600w hps
Temps 24 25 tops,
Humidity 45-50-55% I do struggle with humidity
Ph 5.8 in 6.2 out
Ec0.8 took it to 1.0ec but kept getting darker
So dropped it back down to 0.8, no tips burn/curl tho

So do you think they overfed underfed? Calmag?
Your time is very much appreciated thankyou..

trust your gut here I think... with the deep green, a bit of reaction on a few of the tips and the slight clawing, I would think that they are right on the edge of being just a tad over nuted... but not too bad. Other than that, they look happy and healthy to me.

I dont think they clawing tho, leaves drop a bit but they back up next day
if you think that tho guess ill have to drop the feed again, they only on 0.8ec
So what you think 0.6? Really appreciate your opinion tho thanks

that's what I would try, but I am not always right either. Good luck! you learn nothing without taking some action, even if it means keeping it the same, and at least you are gaining experience and knowledge by watching the results.

I think you would see more damage at this point if that was true. I have also learned over the years that it is best to only try to chase after one ghost at a time... shotgun approach never fully teaches what the problem was, or where the solution actually was found.

What Emilya said!! Try one change at a time. I learned that the hard way. If in doubt, flush well and wait till dryish. Then start lower ec and watch for any changes. Peace!!

 

[Smokes1809]

Ah I'll just drop it to 0.5ec wait till they start yellowing
Then take it back up.. Thanks tho really appreciate your time..
