Im unsure what im doing but this is what i have so...

Hello ! Impossible to grow in coco without knowing your Ph and Ec , exept if you already know the amount of nutrients that will give you the perfect Ph and Ec. For exemple , 10mg of Green house powder feeding in my tape water always give me 6.3ph and 1.4 Ec with 10L but without an ec and a ph meter I would never know it and even if I know it the ph can fluctuate and the ec can be too high if you have a nutrients salt buildup but to know that you need to check your water runoff PH and Ec ( you can have a 6 ph input but a 5.5 output , the same with the ec) . You also need to add cal-mag at each watering/feeding. I hope it will help you 😁👍

hey Coopster, first thing if you can is transfer them as carefully as possible to bigger pots. more space for the roots more space for the buds you know 😄 You want a EC meter, they're quite cheap, same with a ph meter, you can even get the ph strips, which are much cheaper and will last you a life time. you want to be checking incoming and outgoing feeds because they can flip kind of at random. If you can get some you'll want cal mag as soon as possible: just add it to the feed it should fix the lack of cal mag in the coco. And if there s any around you a chelation agent might work wonders like getting some bio fluvic and hummic acid. Good luck man ! 🚀

For hydro or coco, you need a pH meter and an EC/PPM meter. Save yourself the trouble and get a cheap pair, else you will grow blind
