What kind of lighting are you using? From the pics I am guessing LEDs. Are you giving them any Cal/Mag? Growing under LEDs they need more Cal/Mag. :peace:
 
Also have black stains-that seemed to quickly turn into lighter stains and holes. I sprayed my plants with a home made big deterent lemon juice/vinegar/little dish soap. (Very little) it seemed to effect the leaves - but it also resembles a deficiency pic I looked at

It would help if you posted some pictures. Here is a link to posting photos. Photo Gallery Guide - How to Resize, Upload & Post Photos A picture is worth a thousand words!! Also, tell us a little more about your grow. Soil or hydro? Lighting? Strain? Veg or flower? Nutes you are using? All of this information will be relevant to solving your problem. :peace:
 
thank you ya did a hell of a job the pics helped me figure it out I started my grow with two seeds in the window then I got the grow bug lol 16 23wt cfl,s for two plants 2nd week of flowering and bang brown spots on one of the plants I advise everyone to get a ph tester if I had one fropm the start I would never of had this problem
 
This is amazing. I cant believe you put all of this together. I included it in my sig we have to get the word out somehow. Thank you for this beautiful piece of art.
 
Love this post. The biggest thing for the indoor grow, was saved for last. Cleanliness helps more than anything. Before I started growing I got one of Jorge Cervantes books, He stressed clean in the grow room. Careful to change cloths before going into the room. Keep leaf matter and spills cleaned up. And if you have down time between grows wash everything (walls, floors, tools) down with mild bleach solution. I grew for 4 years in a basement, once in a while had spiders and occasional white flies used sticky traps (no poison). Smoke was good.
 
I am noticing some yellowing of the lower leaves. It looks like nitrogen deficiency but, I just feed 2 days ago soil is still moist. root zone ph is 5.0, I will post a pic or two to see if anyone can help me figure it out. BTW only occurring in plants in 3gal plastic pot with roots organic soil.
Possibly need to flush to balance ph of soil?
Any help would be appreciated.
