First dwc grow and having issues?

Hello RIU

I have started my first ever dwc grow and am having some issues!
About ten days ago I got some clones (critical mass and blueberry)
I am using the technaflora recipe for success
Ph has been monitored and adjusted to stay around 5.8
Using recipe at 50% strength and measured ppm at about 650
Using a California led light
Room temp is about 63 and h2o temp about 60
Using air stones
The roots on the critical are coming in nicely
The roots on the blueberry are just starting to drop

Why am I looking so droopy and yellow on the blueberry. I thought I may have burned them in the first three days and subsequently remixed another batch. Anyone have a clue what my issue is?

Thanks to any who reply!

Well your temps are lower then I like to keep them myself (during the day anyways), but I wouldn't think that caused it.
I have had clones do this as well. It seems like genetics has a bit to do with it because in one batch of clones i will have multiple strains, but some strains do it some dont.
Just an observation from experience. Don't worry though, It should come out of it no problem as long as its rooting.

Thanks
Today is day seven with this current mix of nutes. I was thinking about changing them out today but maybe I'm better off letting them go a little further and get more rooted before a new round? I'm going back and forth on whether to make a mix with less ppm or stay were I am around 650 ppm. The critical mass had been droopy at one point but since rooting up they seem to be looking much better.

there is something wrong with your nutes

likely nute burn
650ppm is high for those little girls
I can see the salt build up on the rocks..are those new or have they been used in a previous grow?

technaflora has good nutes but the directions suck bad

tell me what your adding per gallon and how big your reservoir is and I will try and help sort you out

full strength grow formula

so that's
10mls per gallon boost
5mls per gallon grow
1ml per gallon bloom
1 gram per gallon Epsom salt

the P is on the low end which some peeps like.. as long as your ph adjusting with phosphoric acid itll add what you need to the P count

so those little girls should get half strength using these directions.. not the direction they provide, its way to strong

personally I would give them half strength bloom nutes until they got roots and then switch to the veg nutes

I hate to call out ppms on low numbers because no all pens are the same
if you could measure EC I would say feed them about 0.5 EC

Awesome
I switched out nutes last night to 1/3 the recipe strength and it still came out to about 1-1.2 ec on my blue lab trancheon. So you recommend I Ditch there directions and feed your schedule of nutes above. A quick visual on them this morning and they look better already. I'll reduce ec further this evening.
Thanks again

Quick question. I got it down to .6 EC and there already looking better. I was looking at your recommended full strength grow @ 442 ppm and full strength bloom at 342. Is that really all? Those are hugely different numbers versus what technaflora recommends at veg 1100 ppm 2.0 EC and flower of 1430 ppm 2.6 EC
Thanks

Still having issues here!! I witches to RO two nights ago and not seeing any improvement. These plants are 6 weeks into veg and are only about 10 " tall. Seems to me I keep battling nitrogen toxicity? Not sure? I am at .6 EC. Should I just flush with RO with a six ph for a couple of days?
Thanks

@im4satori
Could you tell me if this if schedule you suggested is good for RO as well or should I put the Calmag back in? Thanks

those numbers they suggest are ridiculous

if your growing garden vegetables you need Ec that high but not for pot... its requirements are low


just looked at the pics

ouch

lets go over it all again and see whats going on

give me a few minutes to read over our conversation so I can remember

Great thanks
I have two of the plants in plain ro at 5.8 ph as an experiment. I was going to flush until the morning (10 hours total) and then switch back to a light nute batch. I just mixed up your recipe plus 2.5 ml calmag and 2.5 ml b1 which is coming up at .5 ec that I was thinking about using in the am? or should I fish longer? thanks

ok

I see some of whats happening

theres been some confusion between my directions and your implementation

those pictures/post of the nutrient calculator has got you mixed up

the bottom number that says active elements 342 ppm
that's not at all the same thing as what a ppm meter does
its confusing

EC meter ....means electrical conductivity meter
it measure the electric current in the solution

PPM meter ... converts the EC over to ppm by multiplying it
if I own a ppm meter from blue lab it might convert the EC by a factor of 0.7 where hanna meter might convert he EC by a factor of 0.5

so my ppm meter and your ppm meter might give to different readings in the same solution

therefore EC is always more accurate

PPM meters don't actually read how many PPM are in the solution. its meant to be used more as a reference point when testing samples

the number at the bottom of the calculator is a true active elemental ppm... it tells you exactly how much of everything by converting the % info
it is not meant to be compared to an EC meter or a ppm meter... it is something different

if you took a sample of your solution and brought it to a lab to have it tested... the lab test should yield something close to my calculator along with whatever is in the source water... it is specific....

a ppm/EC meter is just a reference point to tell you if theres a rise of fall in your over all elements it doesn't tell you actual ppm

the whole thing is stupid and who ever came up with the methods should be punished lol

0.5 EC or 0.6 EC was for those tiny little plants you had when you started

by now those plants should be getting the full strength mix

EC 1.0 to 1.2

I have this technaflora kit too, and their recipe is way too strong. It comes out to 2.0+ EC. I just premix a gallon or two per recipe, ph it, then add what I need to get my buckets to the EC I want.
