Yellowing leaves with brown spots high rez pic

Hoping someone could help identify this deficiency. Plant white rino, 3 wk flower, soil 1/2 ffof 1/2 sunshine pro, canna nutes 3/4 strength, soil ph last time I checked 6.3-6.4 two 25 cfm fans running 24/7 in a 5x5 tent, rh 40-50% Thanks for the help

Looks like nute burn to me mate. I would just give them PH,d water for a week then put them back on very weak nutes slowly..

Thats just my opinion mate, see what the others think

Thanks Ipoolfc08 I think maybe you are right, though I am only feeding every other water. Thinking about flushing and give her a break. Thanks again

yeah give them a flush

remember almost all of the answers for these questions about leaves can be found in the First couple threads of plant problems a simple search can find what you need!! other than that yeah it looks like nute burn i would flush for the next 2 water.. also note that this effects the roots than travels to the leaves so dont worry to much if a few more leaves turn up like this its only because the flush has just started

Well I finally figured out what was going on with my plants. I feel like a tard, I used Miracle Grow PERLITE and it has plant food in it. Do they put that shit in all of there products. Anybody know how long that stuff keeps working? I have flushed some of the plants that were affected the most and that seems to of helped. When all else fails read the fucking label. Thanks to all that helped
