the ladies are between 1 and two weeks. the other day i noticed a yellow spot that is now brown. then another plant has a hole leaf that went brown????? any idea on what would cause this? water 2 a week if needed. no added nutrients yet. i use ffof. i really don't want them to die. any help please?

I have 1 doing the same and from what I've been told, it's probably from over watering. Get a moister meter and when you water, water on the outside of the pot so the roots will search out the water and won't be soaked. Also make sure your pots have drainage hole on the bottom to release any excess water so your roots don't drown.
 
Magnesium deficiency it looks like after researching.Either your low on mag. or calcium or the ffof has caused nute lock out, check your ph, these nutes are locked out in soil under 6.4. If thats fine than IDK bro. good luck
 
DO NOT use Ocean Forest to start seedlings! FFOF is a wonderful soil, for plants that are more mature. Definitely high risk of burn when used by itself to start seeds.

Next time use something with virtually NO fertilizers at all. There are many products available that are explicitly labeled for seedlings. To be certain you should check the ingredients of the products you buy.
Fox Farm Ocean Forest: composted forest humus, sphagnum peat moss, Pacific Northwest sea-going fish,crab meal, shrimp meal, earthworm castings, vermiculture compost (bedding material and manure), sandy loam, perlite, fossilized bat guano, granite dust, Norwegian kelp meal, and oyster shell (for pH adjustment).
What is in bold there are all the things that would be providing nutrients and for cannabis seedlings this is extremely likely to be excessive.

The base mix I use for seedlings contains: sphagnum peat moss, perlite, dolomite lime, and an organic wetting agent. Which is Black Gold seedling mix, Sunshine Organic is the same thing and is also widely available. To this I add coir and some earthworm castings, nothing else.

You could (should?) have flushed the instant you noticed the yellow spot, or best case scenario gotten them into a less potent mix. I would still recommend that if they haven't shriveled up entirely yet. There is a chance it could live through this, but it is obviously a major set-back for the poor thing.
 
you won't get magnesium def in the first few weeks from growing in FFOF. Unless of course, if it's locked out.

I've never burned seedlings in FFOF. Not ruling that out though.

What kind of water do you use? the PH may be fucked up if you've been using tap water.

I have heard this many times and I have always used Fox Farm Ocean Forest and never had any problems. Could be the strains I grow I go for hearty strains.
 
well the ph is 6.5. would over water cause this? ffof has not caused any issues that i know have, half of it is perlite......maybe mag deficiency. i have a lot to learn
 
i am going to get a better ph tester tomorrow or monday. the one i have now is a cheap soil one. i will also get some ph up and down. should i flush now? i want to save all that i can of my ladies and the least stress
 
now that i get a better look id probley go get a p.h tester maybe your waters bad and youve got lock out. i didnt see the brown before really looks like lock out
 
I can't believe the bad advice flying around here...
Sure, I can believe that people have successfully used FFOF to start seeds without burning them. Although I do have to wonder whether they did in fact use it entirely alone, and what exactly their germination/survival rate was, and whether they flushed a lot of the nutrients out somehow. I have started seeds in Ocean Forest (+ coco coir) myself when I lacked the awareness to check ingredients; seeds sprouted, within a week they showed signs of burn and the majority shriveled up and died. The ones that did survive were more difficult to maintain and didn't grow/finish to their full potential.
At the very least it is something of a waste. Because, assuming you don't actually loose any seedlings: they're not going to utilize those nutrients very much, if at all. Chances are you will just end up washing a lot of that fertilizer away during those first couple weeks, since the seedling doesn't really have the roots to absorb anything (nor any real need to) until then.

Overwatering? lock-out? deficiencies?...fungus?! I doubt it is any of these things. Plants will show you when they are over-watered when their leaves sag and you know the soil has been soaked for days at a time. Deficiency isn't likely at all for a plant that isn't over two weeks old and still has green cotyledons; FFOF certainly isn't deficient in anything and that includes magnesium or calcium (which is present in earthworm castings and the oyster shell). Lockout would present various odd deficiencies, which a seedling shouldn't be exhibiting...and this doesn't occur when the pH is 6.5.

I would never put hydrogen peroxide in my soil or use pH UP or pH Down. These things are totally unnecessary. Some people do use hydrogen peroxide to keep things sterile, and correct over-watering or give the roots an oxygen boost. This is not a good thing to do when you are using a soil like Ocean Forest. Ocean Forest contains living organisms, as it is supposed to. There is mycorrhizal fungus and all sorts of other beneficial microbes present in this soil that you will be killing if you use hydrogen peroxide and even ph UP. If this is what you want to do, then you are wasting your money buying Ocean Forest to begin with.
I am one of those people who believes (knows) that pH UP and DOWN are not required for organic soil growing...it is an added complication and- in the case of pH UP, potentially detrimental. Don't let your plant(s) form the symbiotic relationship with mycorrhizae and other microbes: which help to break down nutrients and balance uptake, as well as regulate the pH for you- if you're just going to kill them off.
 
ph lockout makes perfectly good since , the ph being to low or high will cause the plant to not be able to take in all the shit it needs.

thanks for the info. i brought up the other ideas to see what kind of feedback i would get and if any one has any good advice. i bought a new ph meter to see how things are.
my last one just checked soil. well if ffof is to strong ill flush it. but, everyone i talk too seems to do well. no matter, i hope i can keep them going.
 
Despite that the provided pictures are small and not of the best quality, to me (and others that posted initially) it looks everything like nutrient burn and nothing like pH problems. And if your pH is around 6.5 like you stated in a previous post then we can be pretty positive it isn't lockout.

I can't say for certain, but I am not sure that a seedling would even exhibit symptoms of lockout if it can still be fed by its cotyledons. Maybe I can do an experiment and intentionally start a seed in a mix with a pH upwards of 7.5 so I can see what happens. I still wont know for about a week though.
And whether it is nutrient burn (which it is) or pH problems (which it isn't) the solution in either case would be to FLUSH with distilled, filtered or reverse osmosis water that is the proper pH (about 6.0).
