Too much nutes then plants burn.
They don't stop taking up nutes.
Flush.

Hey I need help if someone could point me in the right direction of what I’m doing wrong.
this is my first RDWC grow. Have been using supersoil with success prior to this.

planted these 4 clones about a week ago and they all have rooted well into the buckets (except for the smallest one pictured; no roots coming out of the bottom of the basket yet)

they all were doing pretty well initially, and started to look like this yesterday so i did a complete reservoir change just using hydroguard& general hydroponics flora trio and their moderate feed schedule. measured for 20 gallons. (4x 5gal buckets) Also have 5 gal. reservoir

ph = 6.2
Water temp = 74 degrees
Tent temp = 77 degrees
Relative humidity = 44%
Ppm = 430
EC = 860

please help, what am I doing wrong??

plants are steadily growing new leaves but don’t look healthy overall. Some Leaves are brittle to the touch.
ligths are migro array 240w and 12” away from plants

The water temp is a bit high, 70 would be better.
44% RH is way too low for veg. Bump it up to 60 plus if you can.
430ppm is .86ec but nice try, the EC people on here will appreciate that.
Plants look nute and maybe light burned. How about a link to your light?
Gh uses a fairly high ppm so 430 isn’t high for them. What ratios are you using?
Your 5 gallon res tops up with full strength nute solution…or water. If it’s feeding them full bore nutes then that’s a problem. I could never get away with doing nute top ups with the GH FloraNova series; I had to use plain water. Lots of folks use 30% strength solution to top up though, but not full strength.

EC = 860

try about half of that. you nute burned them. i'd give a 12 to 24hr flush and start back at maybe EC of 0.2 to 0.3

FLUSH! I repeat FLUSH. They won't die. Give them 2 days. Then creep up.
They may even give you a BJ.

here’s a link to my light. I have two of these. And i do ph’d water for my top ups.
and what do you mean by what ratio am i using?

 

[DrHill]

thank you, I am going to empty everything out and just use plain tap for now.

 

[rkymtnman]

do 12hrs with tap. then empty everything and do 12 more. then light nutes. baby steps.

Okay, thanks. I am going to empty everything out now and replace with ph tap water

The flora series is a 3 part and there are lots of different ways to mix it, like the Lucas system.
I don’t have much experience with it as I found it burned up my plants, but lots of members on here use it.

gotcha. I’m about to give that a try

less is more in hydro.

GH makes $ by selling nutes.

i just used the ratio they have on the website
I’m using my iPhone right now but roughly estimating

i used about 80ml of micro, 72ml of gro, and 60ml of bloom. In total

All I have around is the printout I used when I ran the nutes before. For the Flora series it lists the dose as 2.5 ml per gallon of each of the 3 for a seedling. That gives you 350-400 ppm (.7-.8ec) depending on your water. That also includes 5ml of diamond nectar and 10 ml of flora blend a gallon to get that ppm number.
They really jump the ppm’s for week 2, 1050-1350. Without including the rest of the products in the line, the 3macros are, 7.5 ml of micro, 10 of gro and still 2.5 of bloom.
So in 20 gallons at the low dose it’d be 50ml of each bottle.
In 20 gallons at the second week dose it’s 150ml micro, 200 of gro, and 50 bloom. Pretty big numbers and not the same as the ones you used. I’m not saying they’re bad, actually yours look pretty good. It‘s just that you’re heavy micro and the old GH charts are heavier gro.

i used 1:1:1 ratio for veg. it was pretty good i thought.

 

[MustGro]

@DrHill I see in the last pic you posted that the solution looks pretty high. What level do you run the solution at?

 

[MustGro]

Do you still run it? I never had a bit of luck with the Flora series, but I loved the FloraNova base.
Probably because I used the fucked up GH charts for the Flora. Your 1:1:1 ratio is basically the seedling ratio. The second week one I posted is 3 parts micro, 4 parts gro and 1 part bloom, that’s way different. No wonder it didn‘t work.

 

[rkymtnman]

yep.

i haven't run it in a while: i had a bunch of free bottles of it from each waterfarm i bought. lol.

I like to get it leveled right at the basket. I’m also trying to get that small one to bring its roots down into its bucket but it’s been a week and they still haven’t broken through the clay pebbles

I ran it higher than normal for that reason, thinking the small one’s roots weren’t getting water & oxygen
