Ianire Posted January 24, 2021 Share Posted January 24, 2021 Hi guys.. just started a grow with coco coir just a small 4 plant operation using a 600w Led light... I'm struggling with all the terminology around feeding and using the nutes that were supplied... it says on the bottle that these are suitable for the whole grow and nothing else is needed.. but I did buy calmag.. I'm hearing alot about vitalink buddy and PK this and that and to be honest my heads spinning a bit lol... can anyone simplify this for me.. I'm currently on week 2 and only maintaining nutes going in and PH'ing them to 5.8 to 6.0.. im growing 1 white widow and 3 LSD all from barneys farm.. lighting schedule is 20/4 moisture is monitored around 50-65. Temp is mid 20s.. any help is much appreciated ✌✌✌ 1 Link to comment Share on other sites More sharing options...

btk1977 Posted February 11, 2021 Share Posted February 11, 2021 Just bare in mind that the doses the nutrient manufacturers recommend tend to be a bit on the high side. Its often best to start at half dose and adjust from there, if they're looking hungry increase it a bit on the other hand if you get tip burn (when the tips of the leaves go brown) then reduce the dose. Reading your plants its one of the most important skills as a home grower and something that takes trial and error and time to get good at. If you have issues with your plants get some photos up on here and we can help. You don't need any of the additives, your a&b grow during the veg phase and then the bloom when you flip (it often doesn't hurt to use a bit of grow during the first couple of weeks after you've flipped as they will still be quite hungry for nitrogen when they're stretching like mad) will do the trick nicely. If you do an online search for your water provider and 'water quality report' you should find a page where you put your postcode in and it will give you a link to your water quality reports which will tell you if you have soft or hard water and give your water's calcium and magnesium levels. This will determine whether or not you need to use calmag (or possibly just mag if in hard water with little to no magnesium). Feel free to post the result of the report here and we can advise on this. One other bit of advice, at this time of year you need to keep a close eye on your root temps when the lights go out as if they get too cold it leads to nutrient lockouts. Try and keep them at 20 or above (if you don';t already have one, get a thermometer with a probe to do this). 3 Link to comment Share on other sites More sharing options...
catweazle1 Posted February 11, 2021 Share Posted February 11, 2021 An ec meter will give you a better picture of the feeding situation. Evaporation can lead to situations where you are feeding too much. Apera, HM and Bluelab make decent ones. The Bluelab Truncheon is the easist to use but it's around 70 quid. 2 Link to comment Share on other sites More sharing options...
badbillybob Posted February 11, 2021 Share Posted February 11, 2021 get yourself a decent ec and ph meter. ignore the feed charts and start at 0.8 ec, see how they go and up it by 0.1 every week or if they start looking hungry (pale leaves in centre of plant) you dont need pk, boost or anything like that. just grow and bloom. add the cal mag if your leaves show brownish spots. good luck 6 Link to comment Share on other sites More sharing options...
lennyd79 Posted February 12, 2021 Share Posted February 12, 2021 Hi pal, I've used Vitalink A&B coir max since I started in Coco a few years ago with very good results. I really recommend using their plant start for seedlings or cuttings, it really helps the initial growth then move onto A&B once your plants have established a bit. I tend to max out at 4.5ml per litre of each, then I taper back down the feed in the last 3 weeks of flowering. I don't need to ph with Vitalink (maybe it's my soft water) I also have never tested my feed for ec as I just read the plants needs by eye. All I use is their Plant start then A&B, I also use their rootstim which is optional. Hope this gives you some guidance, I certainly don't think you need any other additives. 3 Link to comment Share on other sites More sharing options...
btk1977 Posted February 12, 2021 Share Posted February 12, 2021 The one additive I'd definitely recommended getting is a root stimulant. 1 Link to comment Share on other sites More sharing options...

Agreed, but I bought their 'fulvic' which is almost identical to their Root Stim. Plants happy. 2 Link to comment Share on other sites More sharing options...

They both have the same ingredients listed on bottles I just bought the wrong named one that's for coco coir but it does state that the hydro max is for all hydroponics rock wool clay pebbles etc so just need info from you guys... am I missing something?? Both bottles have the exact same ingredients!! Link to comment Share on other sites More sharing options...

It's really up to you what you want to do mate. Edited February 13, 2021 by Xx-Danjaman-xX Link to comment Share on other sites More sharing options...
