hey guys new to this I have some white widow clones!!! getting brown spotes on them!! Thanks for any help!!!
 
pix would help. rust colored speckles/spots are usually a calcium deficiency.
 
Nute burn brother. Flush with clean water and let the roots heal. If you look in the stickies at the top of the forum.. about reading here first... they have pics and the 3rd one looks like your leaves.
 
Ph is a good start what soil what nutes what is ph of your nutes and have you tested your run off water ?
 
i seen Pics now and yes it is Ph the rust look is a tall true sign of ph ..... Ph some water to 6.7 and pour in till runoff comes out bottom for a good 30 secs plant will recover in a week depending on strain..
 
My nuts are foxfarm and my soil is bio bizz all mix I will get my ph reading and post back!! I had a big feeling it was PH!!! Thankyou guys for the help I will post back soon!!
 
foxfarmhard to burn with.
looks like a mxiture of over nuting and PH i had the same problem before

invest in a ph meter, and try using half dosage of foxfarm, when i first started using foxfarm i used full dosage then noticed nute burn on tips and have bein using 1/2 dosage sense.
 
Wow my Ph was way off its at 7.70 so drop the ph to 6.7 flush it for about 30 sec each and it should be ok man good thing I didn't kill them!! Never had a problem until I just moved a few weeks ago! so must be a different water supply!!
 
Water PH can change, I've noticed that after some rain my tap water PH goes from It's normal 7 down to 6, then after a dry spell it can go up to 8.
Now I test it every time,bongsmilie
