Is this nitrogen toxicity and how to fix it

Those are the kind I use

Every time I mist, I get some sort of problems so, I stopped spraying. I figured that the high humidity rising from the DWC provides enough. Maybe I’m wrong but I’ve found that it works out ok.
:wink:

Funny. People mist their plants with a water bottle that has probably been sitting in their tent without aeration and probably transparent to light growing all sorts of nasties. By spraying you are spreading stagnant bacteria all over your plants. Misting is not really required as your plants leaves are perspiring water constantly much like humans do. If you provide enogh water to the roots to absorb the plenty of water to perspire. Check out your plants just as the lights come on and see.

That is a clear case of Nutrient Burn Here is what you do.

Hydro `````````````````
Change out the reservoir, flush out any lines and clean out the entire system and
replace with plain water for the first hour, then start out with lower parts per
million (PPM)
Its good to clean out your system every 2 weeks and replace with fresh water and
nutrients. Some people change everything every week!

Ahh, nute burn! Stop this by not adding to much chemical/organic nutrients to your
water,foliar feeding. DONT feed more than 1 time a week unless using weak amount,
use 1/4 strength for first feeding and then go up to 1/2 strength from then on when
using chemical nutrients. Its very easy to overdo it. Causes leaf tips to appear
yellow or burnt. NEVER give nutrients to plants that are under 2 weeks of age, at
this age the soil nutrients are enough to suppliment them untill 2 weeks of age or
more depending on how good your soil is. Using ferts before 2 weeks will almost
likley kill your plants.
