LostDoja started grow question 3 years ago
Wondering when to add nutrients in coco? I heard after 3rd set of leaves. Some people say after 1st set. I use reverse osmosis with a mineralization filter although I have no idea what minerals are in there. My EC meter did not work when I received it.

My best advice for you is that you go out and get yourself a PH reader. You don't really need a EC/PPM meter if you are using R.O water because R.O water's PPM is like next to 0 . When you start your feeding which you should soon after that tiny second set develops I would start them at 1/4 strength this way you can judge your plants reaction to the nutrient solution and make adjustments as needed , I see your using green planet's line up . If this is the case you can be using root builder and Ocean magic from them right now . Both of these products help with root building as well as nutrient uptake leading into faster and more robust growth . I might also recommend that when its time you start using nutrients that you add CalMg to that solution this way you can prevent the yellowing of the veins in the plant as well as the purpling or all the little stems . The idea is only to really start using nutrients when you see your plant suffering from the start of deficiency's , you're medium should have a base of 1-1-1 which is plenty for the first 2 to 3 weeks even . The main thing you want to remember when they are young like this is not to over water them because when they are young it's really easy to do so . At this stage of their life's less is more . As they get older you can start to up the dosages of your nutrient solution to more appropriate strength . You may also consider wanting to avoid watering them with nutrients every time . This will do 2 things for you a) ensure your plants use up most of the nutrients in the medium before you add new ones in and b) will prevent the soil from getting "hot" and burning your roots leading to what we see as nutrient burn. In between nutrient feedings you wanna feed with PH corrected water so that your plant don't suffer from any stresses or un wanted stunts in growth as well as get any sort of nutrient lock outs which can lead to problems such as nutrient burns . Over all your plants are looking really good and off to a nice start they are a nice colour of green and they aren't stretched to a mile long . I hope this information helps you to understand better when to start using nutrient solutions and how to start them off to dial them in according to your plants needs ! -Happy Growing!

Hi @LostDoja! You should add nutrients in the medium before throwing the seeds. Coco has nothing to offer to the roots, and watering in the first 2-3 days is not recommended, so prepare your medium and water it with nutrients 2-3 days before putting the seeds in. Hope this will help, keep us up-to-date and happy growing :facepunch:

Morning :wave::skin-tone-5:

After 10days regardless of any strain you can start to feed nutrients as for the ph, ec stick, don’t get me wrong there good but I don’t use one, use the old school method.... feed lightly any problems or burning of leafs after feed reduce or give a quick flush to sort lockout of nutrients

Hello! Sorry but without Ec meter in coco you'r done , coco require both nutrients and PH adjustment to work. Not only the input level need to be check but also the output ( water runoff ph and ec can be different from the input) .And if your coco is not pre fertilizer then you need to feed straight from the start with small amount of nuts and increase slowly and don't forget to add cal mag each time you water because coco require a lot.
I hope it will help you :grin::+1:

I was told from a family friend who has been growing for years to start at 1/2 strength after 10-14 days it's worked for me on my first grow and now on the second

For growing in coco you will need am EC / PPM meter (a cheap one will do), else you will have a lot of trouble dialing in the feedings. what you want to do is start feeding right away, focusing on cal / mag on the beginning, around 0.5 EC worth of it (asuming you start with RO water, it should be around 1 ml per liter), or if your tap water is close to 0.5 EC, then don't feed anything. After 10 to 14 days or so (depends on how fast your plants grows), you can start adding growth nutes. Keep in mind that during veg the EC should stay between 0.5 and 1.0 EC. One you get to the preflwoer stretch up it slowly to 1.2 to 1.4 EC; once flowering starts, you can use an EC ranging from 1.4 to 1.8 EC. This are general values, your milleage may vary. Also, when increasing the EC, I would use increases in feed strength of no more than 20%.
