Also keep an eye on your PH levels. Too much of a swing up or down can cause your little one to stress. I had one strain that kept having problems like you are describing and the PH was in check at 5.8-6.0, DWC. I finally dropped the PH down to 5.3-5.4 and never seen anymore signs of brown and yellow spotting. That's just an example of possible problems that can accure.
ok i got a couple pix maybe you can help me out some? cant really see the spotting but obviously the yellowing and brown along the edges.. thx again for the help
You should check your pH, other than that it kinda looks like nute burn. The plant looks quite stretched, unless than was intentional so you could LST it. Make sure your lights aren't too far away as the plant looks stressed
yea i am lsting it an my ph was quite high it has a high alkility so i put a small amount of white vinegar in some water and it lowered the ph so im hoping this will work if not then i will have to flush it an go from there.. thanx for the help
