Cal & mag for calmag deficiency that happen a lot easier in hydro than other mediums & the silica is awesome stuff for strengthening your plants branches so they can hold up monster buds lol ...helps a lot for general vigor in the veg stage .Two essential addatives for DWC IMO :Cool bud:Thanks for the advice DWCocha! So CalMag and silica can act as a Ph buffer? I am bit ignorant of their use anyway.. Why should one use them other than as a buffer?
Hey Lewb12,
just had a quick look through this thread, you said you can only check the levels once late at night. So dosn't the bubbler effect the pH ? i mean if you mix up your solution then test everything, it looks fine then leave maybe it might change. i'm sure i read that somewhere lol Obviously ph effects the uptake of the nutes, everyone knows that, anyway i really wanted to help as i'm intrested in swiching to a bubbler system from soil too in he future so have done a little research.
Anyway probably best just to ignor this ramberling mess.
heres my guide;
yellow leaves = more food
burnt tips = flush then less food
no growth = flush, check the temp in the room then carry on
p.s. oh just thought, what about the temp of the solution the roots are in, do you check that ?
Look forward to pics bro :Sharing One:your right that your EC falling is her taking a bit more feed than water ...thats good Lew ,slightly underfed & a 0.1 drop over a few days is great for young girls .
Yep EC falling & PH rising = underfed
EC rising & PH falling = overfed
Get the EC spot on & PH will stay stable = sweet spot !
I would up the feed but only 0.1-0.2 max (50-100ppm) on your next res change .Once there off & growing 0.2 increase each week is a good rule of thumb & adjust with plain PH water if needed :Sharing One:

Sure is Med .If all goes well in a 20 liter DWC then I would 100% be seeing deficiency by sex without a calmag supplement ,It's gunna vary from grower as everyones water is different ,you may go half the grow & no deff but I wouldn't rely on the trace elements in the tap or the base feed .In my case the 2 separate bottles Canna sell have an insane EC & I cant use them so add AN Sensical right now instead ,starting at week 2 with 3-4ml & working up 1-2ml each week (always adding it first) The silica is optional but good imo . Hope that helpsHey man... I did some study on this matter and I was wondering can you guide me a little here. Canna Aqua Flores already has humic and fulvic acid as well as silicates in it.. I know you use AQUA too so is it just that there is not enough of it?
Another thing about Calmag is that isnt there already plenty of calsium in tap water and most of nutes? Might usual calsium issues be more like lock up problems and therefore solved with proper additives like amino acids or stuff?

Great info, subbed! Congrats on taking the dive into photos too, that what my plan is after this auto run....(gonna run autos between harvest for photos!!) gonna give dwc a try as well..(with autos first, seen seymore-buds grows, and knew him from another site..epic grower!!!!) so trying to mimic that a lil...small setup for now....will consist of 2x4 tent , 2 150 hps, (really wanted to go led, but already have a 150 with new bulb, so cheaper just to buy another 150 , $$ Tight at the moment) & 2 5 gal dwc buckets w/ two 4" air stones per bucket, on a 60l air pump.., still undecided on Nute regime,
.basically starting over, lost all equip in storage, that's another story for another day. Just trying to get max yeild for space I have.., and with what I can afford..
So today's day 18 in veg and she's really coming along nicely if i do say so myself. I've done a res change today and decided to keep her at the same EC and nute sched as the week before (1.3 Ec) starting E.C 0.5.. just because she seemed happy and had only dropped down to 1.2 over the course of a week. Here's a few pics I taken today.
