Suppose if I'm going to buy one anyway, might as well try coco next...

Don't be stubborn like me and put all eggs in one basket

I wish I'd done it a while ago now.

Ahh you using Old Timers. They don't specify what water you should be using but being formulated by a UK grower and to work with UK water, I'd say it would favour hard water over anything. I'd start mixing the RO with tap water 1:1. That will give you a little buffer and should improve things. I'd not bother with the calmag either but that's up to you. RO sometimes causes more problems than good.

Daily feedings make me nervous, I'm quite lazy at times lol.

Thanks S,B I'll start doing that. Will leave out the calmag from now on and see how we go.

Seymore speaks alot of sense there man...first of all id fuck the calmag off as well,just not needed with hard water and yes old timer would have formulated those products for use with shitty uk water,the calmag is more than likely offered for the dutch/euro market who dont have the limestone these shores have,those calmag additives are kinda bullshit anyway,would be much more beneficial to add the cal and mag serperatley in the amounts you needed if you needed too anyhow.....as for ro water..never used it but guess you got mix it with something or its kind of null and void of minerals

You're correct with the RO water. RO water is incredibly pure and contains next to nothing. The trouble is that most bottled nutrients have been formulated for either hard or soft water. Hard being full of crap and soft being less crap. This is normally Calcium and Magnesium but can also be made up of other elements depending on the source. When you use RO water there is 0 of anything so by using these nutrients you will be short of calmag. You can add additional CalMag to compensate for that but it can be hard to find the correct balance. When using soil it took me about 6 months to figure out how much to add depending on the environment, nutrients & soil richness etc. You're much better to just mix the water 1:1 to create soft water and use that or even just use the hard water as is. If you're not using organic fertilisers or going yo be reusing the soil than it really doesn't make any difference. I'm not saying there's no benefits to using RO water but most of the time the complications it brings into your regime far outweigh the benefits.

If you want to use RO water than you will either need to buffer with the correct amount of calmag (can take a lot of work to figure out) or use a nutrient that has been formulated for RO like Terra Aquatica TriPart. TriPart is a three part feed that allows you to tweak things by adding a little more micro into the mix without increasing your NPK too much.

Finally, about flushing with RO, don't do it RO water is a very powerful solvent and it will 100% strip the media of salts but it will do a far too good job and upset the osmosis of the roots. This will slow down if not stop your plants from feeding and shock the shit out of them. I've seen plants go from lush green to yellow and buggered in a couple of days using RO as flush.

@seymore_budz thank you. Ill ditch the RO for now and see how the tap water fares for the rest of this grow. Im going to invest in an ec pen in the near future and will probably enjoy experimenting with RO in the future as well as a multitude of growing styles. Yeild isnt super important so i dont mind screwing things up.
Big thanks for the effort put into your replies easy for a simpleton like me to understand.
