Leaf Issues. Please Help..

Have been noticing these spots on my two girls. The closest ones to the fan, wind burn??, about 16" maybe less away from 600w mh. Other plants are doing just fine so far and are about 11" but not close to the fan. Bleaching cause they may be more sensitive or what? Maybe ppms too high..1340 and 1430. Fox farm soil. straight out the bag at 23 days in. There in 4gal pots. Maybe hot spot in the soil? Water ph'd around 6.5 7. Idk but help a dude in need. Plus rep to answers. Thanks!

Are all ur plants the same strain? Maybe that one likes the mg, it looks like my mg deficiency I had when it started. Have u inspected thoroughly for spidermites? Just a thought

Fox Farm just ain't what it used to beYou haven't feed rightIf not feed grow big 1.5 tsp & 2 tbs big bloomGood Luck

nah got a few different ones. the ones that are being effected are grown in soil. Gnat Farm, i mean fox farm. but it sure isnt the same like it use to be. The violator kush is the worse one then the Pineapple Express slightly then a greenhouse Kings Kush that like a runt from the get go. The hydro, Pineapple Express is doing excellent. no issues that are of concern as of yet. But maybe its just the soil. Some of the leafs feel slightly dry to the touch. But mainly the older ones that seem to be affected. So your going with MG deficiency huh? Fan isnt an issue or even the light? At first i thought maybe its from when my hands are wet or a splash of water gets on the leaves and creates an magnifying type of thing with the light and the drops of water and maybe thats how it burned idk. Next time im gonna do just DWC, much easier in a way but better results so far. Thanks. ps...yea ive checked for spidermites on the majority of my girls. Didn't see any issue of the sort, so far. Hopefully i never do. All of the leaves "seem" clear when viewing from the underside.

Nope sure isn't. Whats a good one for the next time i need to use one? But nahh i havent fed them anything as of yet due to the runoff still being in the 1200-1400 range including tap ppm. Not sure if i wanna add any ferts cause im worried of burning them even more so. With there still plenty of food in the soil maybe ill do a flush to lower my ppms to where i can feed...ah ha..idk lol

Feed'emAre the stems soft & rubbery?Slow growthBeen there I'm just finishing up my last grow with ffofThey keep itI had low ph & low phAdd 4 cups of llime total to each 5 gallon pot 1 cup at a time and the ph is still lowI used to love it here is a link to my first grow of ffof~my first video is before they were feed & my 2nd video is after the were feed you should watch'em~The first video looks like yours

Thanks. Will watch and get right back to you. But no, the stems are actually a nice size. Not flimsy at all. Side growth is great. Growth has not slowed at all. They're just starting to developed that shit on em

looks good. how much u yield of those five? whats the strain?

NEVERmind i saw the vids. Nice, def sativas lol

Yea bro it may be from a splash of water or something like that. I'm not sure about heat with a 600, but if it was burnt from just the light itd start on leaf tips. But every mg def I get it always starts with small brown spots that look similar to a burn but they'll be in the middle of the leaf. And then yellowing would start. But there's a # of things of could be I guess

What you have is a little too much of this or not enough of that
Basically your plants look great. I wouldn't worry about the small spots

I would have to agree with dannyboy. I'm sure u want em perfect but they do look great

Rust fungus is somewhat similar, however, would appear much more severe (you can see examples on google images). I have two rose bushes completely swamped by the rust fungus, and I can almost completely guarantee that this your plant is not suffering from the rust fungi. I would agree with dannyboy602, don't worry about it. I have seen these spots on many plants when doing research for my grow. Even my week 7 plants have a few tiny spots like this of their own now.

Clone it and start another one.

?? Why u say that stunk

dont knw if this helps but ive figured out why i had brown spots (or atleast i think i did they havent came back) before my light turns off i sprayed them with my foiler spray and pretty sure it was burning them. I dont knw if you spray your plants but if you do dont spray them with the light on.

I used to think you could use the "run off ppm" It can't be accurate I just did a test of sunshine mix 4 on another thread on this page its right. The ppm of sunshine mix 4 was 510 ppm and it supposed not to have nutes in it so whats all the ppm. I going to get a link to the thread hang on
