Black and RUnner: are you the same person? Very confusing here! lol
Stich we are two different people. I just realized my pictures are not visible anymore? Can anyone explain what's the correct way to upload pictures on to the this thread?
Black and RUnner: are you the same person? Very confusing here! lol
However like I said I haven't calibrated it since I have troubles finding a calibrating liquid.
Stich im hoping you could help me. Im pretty new to this but ive helped with a few grows previously, just never DWC. But i have read what fells like every thread in the past few months on this and other websites in an effort to learn.
I built a 24 bucket rec. DWC system almost identical to Blazes tutorial. I got my Blueberry clones in 1 inch RW cubes and put them in 6" baskets about 1 inch form the bottom of the net pot and my water level is about 1 inch under the bottom of the net pot. the first couple of days were tricky for me becuase i didnt want to overwater the cubes so i ended up underwatering them as the cubes were two high(originally 2 inches from bottom of net pot)
I lowered the cubes and the roots started to come out the pots like crazy a couple of days ago. What i notcied is that the plants with the roots that first started to reach the water/nutes started to show yellowing on the new growth. The yellowing starts at the bottom of the leaf and progresses towards the tip. When they hit the water/nutes i was feeding 480ppm at about 5.3-5.5ph. Yesterday I added nutes and raised the ppm to 650, but today the yellowing is spreading. Today almost all the plants have reached the water/nutes and they are all pretty much showing the same problem. After reading your original post, sulfer is the only thing that occured to me but i wanted to get your opnion before starting to add epsom salt to my feeding tank. i will upload pics shortly.

With your water being hard, you should not have a sulfur problem. It's rate for a plant to show sulfur in hydro, unless it's growing in a hydro hut lol
Sounds to me it may be a nitrogen problem...... Are the rock wool cubes the same color? No greenish? Dug up some of the hydroton until i got to the rockwool cubes and i found their color unchanged altough the were damp but definately not soaked). Im not sure if the objective is to maintin the rockwool dry at this point since the roots are well into the nutes?
Sometimes using RO water on newly rooted clones can get the same effect seedlings have, using RO water on seedlings and newly rooted clones I would not recommend, due to low micro nutrient count and can contribute to slower rooting time and nitrogen deficiency problems.
I am not saying this is what your problem is yet until I see pictures; I can only go by what you tell me at this point. You say you are using RO, then you say your ppms at 250..... you using tap or ro or both? im only using ro water. My tap water before running through the ro filter is 250. After the ro its about 40 or so.
The temps have to definitely come down, otherwise you will have root rot on your hands eventually and it's a bitch, cause the whole system will need sanitized and with the # of buckets/plants you got..... You will not be a happy camper!! I expect to have this under control in the next 48 hours.
What are you using to keep the temps down? You want the water temps 65-70F I have a 1/4 hp water chiller.
If the yellowing is starting at the bottom, it sounds like nitrogen.... weather it be from low ppm or the RO slowing the rooting process down.... not sure yet. No No the yellowing is starting at the base of the new growth and progressing towards the tips. When i wrote bottom, I meant base. There is actaully no yellowing on the bottom fan leaves.
I always tell people to mix tap water/ro or tap/distilled ratio so the micros in there to help with the rooting.....
Hi Stitch,
Yeah I'm in Europe, sort of. Not the most advanced part of it so all the goodies like SM-90 are out of question. Currently I'm not using anything to cool the water down but I plan to put ice near reservoirs, open cabinets doors, open windows etc. Do ou know of any other methods? When you say I need to rinse everything water came into contact with by water you mean nutrient solution or the h202 solution I'll dip the roots into and if its nutrient should I pour water through the medium to wash it up? Also is it ok to dip the bottom of the pot in h202 so that bottom part of the medium is soaked? There is an algea in the medium, should i do something to get rid of it?
Hi Stitch,
They should pay you for the amount of work you put in here, bro. Thanks and much respect. Question: on a scale of 1-10, how much stress would it be on a plant that was cloned aeroponically, vegged aeroponically with high sustained CO2, to be transplanted at around 15"-20" from the Aeroflo into a 4-gallon ebb-n-grow bucket with coco chips? Was thinking of using the Aeroflo for veg only, flower in something bigger and almost as oxygen-rich (coco chips almost the size of croutons)...
Hello all I hope someone can help me
* Hydro or Soil - Soil, Roots Organics straight out of the bag, 3 gallon Smart Pots
* Type of light? - Sunleaves Pioneer VIII Grow 4' 8 tube T5 fluor veg bulbs, running 24h a day
* "Atmosphere" Conditions - 5'x10'x8' room, 177 CFM (after filter) inline fan, carbon filter, 2 oscillating fans, air temp 75 F, humidity 42%, temp and humidity do not vary much
* Watering - Using tap water that has sat in open container at least 24h, I think I was over watering (1 quart per plant per day) but now I only water when they feel light and start to droop, using 3 gallon Smart Pots

I have been watering with straight water for the last two weeks except last night I used the nutes listed above but forgot to add the Cal-Mag.
More pics in the link in my sig, thanks all.
BTW.The three pics labled "sulfer deficiency" are the ones that I previously attempted to load.
The pictures labled "four days later" show what the same plant looks like today. This is four days after raising the ppm from 650 to 750 with dissolved epsom salt (roughly 1/2 teaspoon per gallon). I also stopped trying to get my ph down to 5.3 everyday. I havent phed in five days and the ph slowly floated up to 5.7/5.8 and it has mainted itself the last few days without changing. STRANGE? The yellowing at the base of the previuosly affected leaves has been pushed out near the tips. Because of how long it took me to load the pictures in order to get your opinion, I was forced to take action.
The yellowing on the new growth has seamingly been resolved but now some plants are shaped like a V. Magensium deficiency? uploaded two pics labeled "new deficiency" I dont know if this is a product of mainitng the ph at 5.7/5.8 for so many days? Is that a bad thing?
How often are you feeding and how are you testing your pH?
Overwatering will cause nitrogen deficiency like you see there, with the amount of nutes you are using, the reason why you are not seeing a burn, is because you were watering frequency,... you should go by the size of your plants not the directions in your situation.......
Have you tested your TDS of your tap water?
The other picture looks like a magnesium problem.... start adding some cal mag... but important thing now is how often are you feeding them?
Watering - Using tap water that has sat in open container at least 24h, I think I was over watering (1 quart per plant per day) but now I only water when they feel light and start to droop, using 3 gallon Smart Pots
No, you stated in the post that you were overwatering, nitrogen has problems getting absorbed when the soil is wet frequently, I did not say that your problem now is over watered...
but the yellow leaves is a nitrogen problem that WAS caused by overwatering, nitrogen affected leaves do not recover and stay that way and eventually fall off after the plant is finished with it.
If you have to water your plants everyday then the plants are rootbound...Not saying this has to do with your case, just saying for future information
smaller plants should not need watering everyday.... your plants tell all and so forth.....
How often are you feeding your plants? That dosage you give for the size of the plant is kinda high........
Wait got the pictures now!
FIrst stop keeping it that acidic....... another thing the pictures are so dull I can't tel if it's yellow or whitish yellow......
If your pH is being maintained then your plants are using more water then nutrients which points to too high of nutrient solution..
Either your pH is causing this from you constantly trying to keep the pH at a certain level, of this is light bleaching..... you should never see a sulfur problem in hydro unless your plants were in PVC grow tents/huts.......
First flush the system out and add fresh... I know it sounds like a pain, what are you using for pH adjusting.....
If you contacntly adjust the pH and depending on how much of it you use it may build up...
You take your nutes and add what you need then check the pH and TDS..... the pH will raise when plants remove nutrients..... so when you add more nutrients check the pH and adjust when needed...... never use high nutrient levels to adjust the pH.
Hydro you can have a pH range of 5.5 to 6.3... if that is a sulfur problem, it's due to having a low pH, so raise it to around 5.5 to 6.2
Try 6.0 pH if you can't get it there but just under it like 5.8 that is fine too.
Using high levels of pH adjuster all the time is not good.....
Another thing that is kind of confusing you stated this :
Is your water HARD or SOFT? 8.0/250PPM BEFORE RUNNING RO 8.0/40 AFTER
Are you using RO water or tap? Are you sure all your water that is coming out 40 ppm?
Hard water will make it nearly impossible to grow in hydro due to high mineral content and high pH; so by using lots of pH adjusters it causes problems and it's hard to bring the pH down to the proper level....
Thank you for taking the time, it is much appreciated
Correct, I believe I had been over watering in the past but I am not watering until they are very dry now.
I am using nutes every time I water, is this wrong? Should I alternate with straight water? (I am such a noob)
Should I cut nutes in half? I was going by the Roots Organics feeding schedule but still using the 3-4 week dose even though I am into the fifth week.
Do they seem small for 5 weeks?
On a kind of related topic, how long can I veg for? I am under 24/0
