so you think i should just go with a camg only supliment? my issue is that i dont have a bunch of cash to spend on my project anymore. so if im going to buy something it would be more benificial to me to get a all in one so i dont have to concenr myself with buuying anything else down the road.

the dyna gro im using is supposed to have trace elements in it as well.

As I've mentioned most nutes have enough micros already.

I really do think your issue is your exceedingly clean well water not having a high enough ppm.


When nute manufacturers supply hard and soft water variations the only real difference between them is the Ca and Mg content.

well its a rather large res so i bought some dutch master zone to help avoid contant rez changes to save a little money on wasting nutes.

tbh when i said around 650 the other day it was closer to 670 anyways, they may have gone up a little but no more than 5-10. ill empty out 5 gal later today and replace with clean water to see if i can get the ppm back down tot he 500's

all in all though the discoloration is not spreading much if at all and the new growth seems to look a bit light compared to some of the older growth. get paid bi weekly and will be placing an orfer for a fresh bottle of Dyna grow-grow and ill save my 50/50 mix for when i flip the lights to 12/12 i fiigure i should have to change the rez once and thats when i flip so i can do a different nutrient regiment, after that change the plant should be drinking enough water where i can add 100% bloom nutes a couple weeks later.

so you think i shouldnt bother with that micro nutrient i linked above? or would it be a good preventive to add, even if im only adding 1/8th of recomended dosage.

Personally I wouldn't worry about the micro.

ok so i never really emptied out any water..did my tests today and the ppm went down from 670's to 630's so it is gradually dropping. last i checked was 6 days ago so.

still seeing some issues but overall plant health remains good.

As long as you remain with a drop in ppm then you'll be fine.

As soon as ppm's start to increase, water it down to reduce the ppm's further than they were.

Really you should dump and refill once a week, how do you know each element is being uptaken at the same rate, leaving the same concentration behind?

N, P, K, Ca, Mg are uptaken at different rates depending upon plant growth.

If you don't dump and refill regularly you could have a build up of anyone of the macro's as the others might be being taken by the plant.

yeah im lazy lol but i will heed your advice and do a rez change tonight. i need this plant to grow top notch...i dont know about changing a 30gal rez once a week for one plant but ill prob do it every couple weeks from here on out.

Yeah 30g is a prett good buffer.

You could probably change out 20% or so every week and be ok.

But if growth is stagnating or plants look worse then dump the lot and replenish.

im just gonna rez change theres some coloration i dont care for going on

also be ordering them micro nutes despite you saying i dont need them i feel it cant really hurt to have a little in there.

That's the point, you already have a little in there from your nutes.

But let me know how you get on with them.

Ever had a micro def while growing?

Is this your first time running DWC?

i have had all sorts of issues while growing.

this is my second DWC grow but i made a pretty large scale fail with my RDWC system i built...root rot issues, thats why i went with the dutch master zone for the rez.

I changed my rez today full change dropped the PPM down to 600 (whats your opinion on that low?) switched to flower a week ago today so i just added the same nutes that were in it (remember i said i was using a mix of 50/50 bloom/veg) fig ill dump that in 2 weeks and add straight bloom after that but i do want some stretching to take place so i fig the extra N will be goof for that.

also did NOT any more of that cal/mg powder pill stuff i was talking about earlier. I will wait till i get the micro and just use that.

dont take me the wrong way with the micro. I do value and thank you for your input thus far. I wont use alot of it if the bottle calls for a mil a gal ill prob use 2 mil in the 20 gal of water i have.. Dont want you to think im ignoring your advice as im actually listening, just want to make sure and i know it wont hurt anything using such low amounts.

also what are your opinions on boosters after week 4 of bloom? do you think they help or no? i have always been really iffy on them as i feel the plant is going to wind up the same no matter....havent seen any side by sides (in a good controlled experiment) so hard to say.

People would kill for my water lol.....did a rez changed brought the PPM up to around 600 added the zone and checked the PH. 5.7!! im sure it will go up a little in the coming days but man cant get any better than that. and the rez i just dumped never went over 6.0 and it has been about a month since i filled it for the first time.

You do realise the micro nutes shouldn't really contain any Ca or Mg as they are macros.

If you've just switched to flower watch your ppm's as they could decrease quite drastically over the coming few days.

I generally bump up my ppm during stretch and then taper it off a little after the stretch.

Boosters.
It depends entirely on the PK contained in your base nutes.

My NPK is 5-4-3.

So I like to hit mine around week 5 of flower with PK1314 for about 1 week.

the dyna grow bloom is a 3-12-6 think thats enough Potash ? or think jusy a K booster would be appropriate or think it should be fine throughout?

think i should increase PPM to 800?

im going to hold off on the micro stuff as you have convinced me otherwise, and we came into a few extra bucks and the wifey said she would allow a seed purchase so i need to pick my batlles lol.

3-12-6 seems hellishly low on N sustain vigorous flowering.

Too high in P compared to N.

I would expect something around 6-3-9 to not require any boosters during flowering.

I've had great succes with a 6-3-8 hydro veg formula from start to finish.


Only increase ppm when you're seeing ppm decrease in your 30g res by more than 100ppm.
