Hey,
I just posted on another persons thread.
Similar problems to you. Maybe this might help you too.

I will admit that I am fairly new to this game and learning as I go along but I think I found an article that might help you figure out what wrong.
Have a look here and see what it most closely resembles. Plant Abuse Chart and Photos by Nietzsche

I hope you find what you are looking for in there. I think he/she did a good job in pointing out the main problems.

This deals with deficiencies and overdoses and not parasites.

I also have a grow going on and your feedback would be much appreciated.

Its here : LED LOGGER

I hope I may have helped in some way.

Take care

I hope this helps and gets you back on track asap !

Take Care.

Hey Tentman, I must admit, I am very impressed. You found the canna.com troubleshooters guide and posted right off the bat. Nice work. I have a bit of trouble finding it at times!

Nice link SL, will be looking in on your grow, as well. If you could kindly start a thread, I am sure Tentman and some of the very expert growers and us, not so expert, will follow you along and the confident great growers will give advice as needed or cudos for nice grow! pr

I may be way off-base here, I grow in soil.
But, aren't you supposed to adjust pH to hydro levels, when growing in Coco? pHing your nutes/water to 6.5 is perfect for soil, I'm thinking it should be lower for coco.
IMO it also looks a little bit like over watering, is the Coco drying out enough between waterings?

i think i may have overwated with too much nutes early but have flushed them since.they seem too be getting better. just not sure when i should try feed them nutes again. worried about the same thing happening when they just getting better.
