I'm having problems with my first time grow and haven't got a clue what it Is? Done loads of research but still haven't a clue so I can't correct the problem until I know what it is and what's the cause? Last night I noticed a dark brown/black tiny spot on a leaf and then on another leaf I noticed the stem of the leaf had like a rusty brown area of it..now today.. the rusty patch on the leaf steam is spreading outwards (like little patches of it spreading outwards) and also it's starting to spread onto other leafs..if it gets worse by tomorrow which I'm pretty sure it will..and I'm no closer to finding out what it is, then I'm going to have to flush the plants with plain ph'd water.. they're in 15ltr pots with Coco being my medium.. my question is..how many little of water should i use to flush the 15 ltr pots? And also should I flush all in 1 go? Or do it gradually throughout the day e.g 1 litre every 1-2 hour throughout the day? Here are some pics..
First grow problems..what is it?What should I do?

That isn't anything to worry about....honestly, the symptoms are so small and minutne that I can barely even see them. Its really hard not to overreact, even when it's NOT your first grow, but I promise the grow will go far more smooth for both you and your babies if you relax and let them do their thing. Your plants are fine, I wouldn't worry unless it actually begins to affect the greenery of your leaves and/or you start losing leaves. Flushing will do you more harm than good. Just extra stress.
Ok mate cheers for the advice..glad you posted because I was literally minutes away from flushing lol, it is spreading to the odd other leaves..but it's hard to see like I have to get right close up to them to see it..il just leave flushing then an see how they go..

I'm sure there is something going on here causing those blemishes, but I just don't think it warrants flushing *yet*. I could be totally wrong here, but I would see if your plant grows out of it..I get weird little blemishes around the main vein going down the center of the leaves sometimes...but unless they're making your leaves go yellow or something, I wouldn't fret. Have you checked the under sides of your leaves for any critters? I know that bugs can cause a lot of symptoms along the veins of your plants as thats where a lot of bugs sug out the juices.
crazy you just saying that about there being any critters mate as I've just noticed this on one of the leaves as I read your message.. that could be part of the problem but I also think there's something else wrong as I've just noticed this on a lower leaf..

Oh man, you're going columbo (peter falk, old timer i guess lol) around her lol
The bugs you would generally worry about are microscopic or very tiny in nature. I think that was just a normal house fly type that got in and you sentenced it to death I don't think you have anything to worry about, those tiny minor blemishes happen on leaves. Look in nature, bushes or trees will always have some tiny leaf marks or blemishes, nothing is completely perfect! Check the underside of the leaves with a scope for critters to be safe. Also, check your temps/humidity, the leaves are showing some slight curling at the edges related to overheat and/or low humidity.
Oh, btw, i wouldn't flush, leaves seem nice and healthy, if there is an issue, it would be on the leaf/surrounding growing area (if it is bugs), not an issue with nutrients in your medium.

I never grew in coco before but looking at the tip of some leaves, could be you have a slight nute burn.
I also would not worry much at this point - Just let them be and watch out for evolution.
Your right there matey an also that's what everyone else has been saying about not worrying but it's spreading.. instead of flushing them in one go I've decided to just give them plain water for a few days..maybe rest of this week an then start giving them canna coco nutrients that I've just orderd..because that nute burn is from giving them 1/4 of the amount that it says on biobizz nutrient schedule..absolutely hate biobizz..wouldn't recommend them to anyone..infact il just through all the biobizz nutes I have..wouldnt risk giving them away in case they mess up other people's plants..ive had nothing but problems from day one with them!

I'm interested why you think flushing is the answer to everything, because you're probably hurting your plants more than helping when you just do a flush out of the blue Vinny

Good idea - Plain water for the next 2 or 3 waterings (please do not water everyday except if you are in a really small pot which you are not with a 15lt one - Watering once every 2-3 days should be enough) should tell you if the problem persists.
Which strain is that? If it was an auto careful, they are very sensitive to nutes.
I normally grow autos in soil and some strains get burnt with 1/4 strength nutes every other watering!!
Fair point..I'm just new to it but il take your advice..what should I do about it? Here are some more pics

Cheers for advice mate! Yeah your definatly right every single day is too much..I water every 3 days..take a look at the pics I've just uploaded to this thread..getting worse by the day
It's white widow X big bud xl by the way mate an it's a photoperiod plant

Firstly, don't water with just pH'd water...you're only going to hurt the plants even more! This isn't a soil grow, so don't treat it as such. While I'm sure everyone here is trying to help, you need to be able to sort through the good information vs. bad. There are no nutrients in coco outside of what you add in your feed / water. If you stop providing nutrition to the plants, what do you think will happen? They will immediately begin to decline. Ideally you should be feeding / watering every day; this is the beauty of coco (air to water ratio), and this is what allows one to experience the gains over a soil grow in terms of growth rates, etc. This is also why pot size choice is paramount, too small and you're feeding / watering sometimes 2 or 3 times per day. Too large and it remains too damp for too long. Balance is everything in coco. If you think you're over feeding them, reduce their feed, but don't cut it out all together; you'll only make things worse. Secondly, your pictures in general look fine. I wouldn't sweat it over small blemishes. Concentrate your attention on the new growth of the plants. If the new growth is green and healthy, you're in an ok place. Thirdly, If you don't like the nutrients you're using and you have an option to change them; go for it. And if you're still nervous about things, post some pictures of the full plants, in natural light and give the specifics of your grow (coco used, did you rinse out the coco before using it, what is your feed / water pH, exactly what are you feeding them, how much, etc). I'm sure if there's an issue, it can be sorted out.
Never thought of it like that, I've been using biobizz bio grow an bio bloom but only giving them quatre of the recommended dose, that's one thing I didnt do is rinse the coco First..how would I go about doing this?? I've got another bag on "plant it" brand coco that says pre washed on the bag.. so does this mean it doesn't have to be rinsed?Or shall I rinse it just to be on the safe side? I've got some canna coco nutrients coming tomorrow..so I will use that for the rest of the grow

GH Two part Grow/Bloom formula allllllll the way
A truely idiot-proof nutrient line, one grow bottle, one bloom bottle. Lord knows I need an idiot-proof brand of nutes...Wish I knew about GH before I ordered canna coco nutrients lolGH Two part Grow/Bloom formula allllllll the way

Haha well I've heard a lot of good about Canna as well, so I'm sure that it'll work well!

I don't use GH or Canna ( I use Jack's 3 2 1), but I've heard good things about both, so I wouldn't sweat using either or. As to rinsing out your coco before you use it... I know there are some brands that say they've been rinsed, buffered, etc, and just off assumption, I guess this is true. But for me; it makes more sense just to rinse the coco out, regardless of the manufacture's claim, if for just my own peace of mind. I use the dehydrated blocks myself which generally aren't noted as being rinsed, but I've also used higher end coco which was supposedly rinsed and I rinsed it myself anyhow. This is how I do it: I take a 4 - 5 gallon pot, line it with a cotton pillow case, pour in my coco and then rinse the heck out of it (just using my tap water) until all the tannins / color comes out of it. In other words, I rinse until the run off is clear. Now the coco has taken on the makeup of my tap water (probably @ 7.5 pH) Then I charge the coco by pouring feed through it. So for example, if I'm putting clones or older seedlings into the new coco, I'll mix up a 50% solution of feed and pour it through the coco, before putting the plants in it. Now the coco has pretty much taken on the makeup of my feed (5.8 pH). It will have the same relative pH as my feed and it will contain all the nutrients that make up my feed. Then I'll plant the clones, seedlings, whatever and feed again immediately. At this point the coco is pretty well rinsed, charged and at an ideal pH and nutrient range for the plants. When I do this, they won't miss a beat. If I fail to rinse, I will have issues, which will generally hinder the plants for a couple of weeks until things balance out. In a nut shell that's how I do things. I'm sure there are those who don't rinse, don't bother with the dehydrated blocks, only buy pre rinsed coco, rinse like hell, etc, etc, etc...this method works for me, but at the end of the day, it's all about skinning the cat, no matter the means. Hope this helps.
