Okay thank you. I’ve got a lot to learn. I didn’t check ph on pellets. But I did wash them off. I still don’t really understand the ppm thing. I’ve tried watching videos on it and just really doesn’t go into my head. I’ve sprayed the top of my coco now with some ph’d water. Should I do that every day or actually water the full potCouple of things bothering me when I look at your pics.
1. Your hydroton (clay pellets). Did you clean and check the ph on them before you used them? Because they look dirty to me. They tend to absorb minerals over time and cause massive ph swings up. I think this is especially true when they dry out. Which brings me to:
2. Your coco is dry. It's damn near impossible to over water coco. When coco dries out, BAD THINGS HAPPEN. Dry coco has a crap cation exchange capacity and is full of salts which locks out beneficals like calmag and iron and again screws up your ph. It's a lot easier to deal with when you start in smaller pots and then transplant into bigger as they grow. You need to keep the all the media in your pot wet and fertigate multiple times a day.

Here they are@Cottygrower - Do you have any recent pictures? I'd like to see how your plant has grown.

So, here is my take on your grow so far. For starters your pots are too big for early stage of development. I usually start my seedlings in a red solo cup. The next thing is I would water only when your plants are thirsty. To tell when they are needing water insert your finger in soil to the first knuckle, if you feel moisture don’t water.Here they are
Thank you I found this very helpful. What is the easiest way to grow weed for a beginner. I want nice smokable buds. Not bothered about it being top shelf. I’m doing this to help save me money in future. Also really starting to fall in love with growing. It’s just so complicated at times. I’ll do another post this week explaining everything I’ve used. So in future you will all be able to work out where I’ve gone wrong. Thank you all tho for you advice. It’s a lot to take in right now but I will figure this shiiit out.Hey cottygrower I see a lot of guys chimed in a bit early making recommendations before your media and nutrition was mentioned.
Seems to be happening a lot lately.
Stanknkatz has it correct. You are going to need to feed your coco at least daily and the big fact is that they do better with multiple fertigations daily.
This does not mean start pouring nutes and water in the pot. It means you need to read and process how to grow in coco to be a grower in coco.
I would like to touch on a couple of other things that new growers sometimes miss.
Coco also needs a prep to be effective growing cannabis. Coco is inert and holds very few nutrients. The type of coco you purchased is important for later in the grow.
If you can post the bag of coco you used that would be great. We need to know if the coco was pre buffered and soaked with cal-mag before putting it into use.
The very few nutrients that coco tends to hold onto are magnesium and calcium and these need to be added back into the coco or supplemented with your nutrition. Even soaking will not normally last the whole grow but if it was not soaked by the time you get it to about 3rd or 4th node level it will prolly go tiger striped and start with the rusted pinholes.
Now.
If you read up on coco and it does not sink in you can run coco with just a pH pen but you will have to be able to identify hot nute and lack of nute presentations ( how it looks ) in your grow and adjust the nutrition mix.
If this is something you can not do ( do not want to learn ) there are other ways to grow cannabis that are less technical or rely on experience that you will grow into but do not yet have.
Good luck!
Ok I want you to find your grow style.Thank you I found this very helpful. What is the easiest way to grow weed for a beginner. I want nice smokable buds. Not bothered about it being top shelf.

See those 3 horizontal bars up top of the page? Hit that and navigate to the forums section and look around for grow diaries. Once you are in grow diaries use the spyglass to tag jeywords look up organic growing , fox farms, and organic nutrients. This will populate grow diaries and you can see how long and how much work it will take you.
Then search for living soil and build a soil. Again see how living soil is made and see how all you do is add water.
Both these methods will require minimal tools and as long as you can measure and follow directions you should do well.
Good luck.
I have used 20l fabric pots. I used about 2.5l of pebbles in each pot. I didn’t do anything to the coco before starting. But I washed the pebbles (did not check ph) then put my seeds in some water for about 18/24 hours till they popped. Now running my light at about 40% (think it’s a 320w light) it’s 2ft away from the plants. Cycle is 18/6. Running my humidifier at 65/70%. Temp with lights on is around 23’c to 25’c lights off drops to around 18’c/19’c. I’ve used a very diluted mix of grow nutrients. The same I mentioned before. Only feeding them when they dry out. Also spraying the top layer of coco every 2 days to stop it drying out.Hey cottygrower I see a lot of guys chimed in a bit early making recommendations before your media and nutrition was mentioned.

Perfect thank you. I do have calEcothrive Coco Lite is pre buffered, so that helps. You're still most likely going to need cal mag in the future, so take that under advisement. You also are going to need a good ph/EC meter. I know it can be confusing, but after a bit you'll understand what ppms are and how to handle it if you stick with it and are willing to learn.
This page may shed even more light on your situation, seedlings in coco. You should take a look at the page on high frequency fertigation in coco also.

Understanding ppm is easier than you might think. As stated, it means parts per million. So, with your ppm reader (pen) you find out your ppm reading with the water on its own. Then when you add nutrients to the water, you again read the ppm. If you subtract what the original reading was, that's how much nutrients are in the water.Okay thank you. I’ve got a lot to learn. I didn’t check ph on pellets. But I did wash them off. I still don’t really understand the ppm thing. I’ve tried watching videos on it and just really doesn’t go into my head.

Yeah same ratio. The one on the left (smaller one) has always been behind the one on the right. But I feed them both the sameAre u feeding them the same ratio, ? the smaller plant might be overfeed.
Perfect thank you @WinJr63. They are currently on week 4 of veg. Do you have any tips for when is best to change into 12/12. I’d normally flip the lights when the plants are roughly 1/4 of the size of my tent in height. Just wondering if you recommend any other way to tell whenBoth plants look great actually, new growth, keep eye on for changes.
