Right off the get go I'm gonna say it's not your watering times it's your PH. Also did you soak RW in PH'd water?? How often are you watering them now?? How old are they?? Are they on nutes and if so at what mixture and type, also list additives if any kk?? What is the PH of your water that you give the plants and if it is adjusted what was starting PH and where water from (tap, rain, neighbors pool, etc)?? That is just a min for water.
Chapter 2:
Lights-
What kind and what wattage are your lights?? Time on and time off?? Distance form top of plants?? Are they air cooled?? What is temp range in grow area (lights on/off)?? Is air circulated inside grow area?? Is the area vented??

One thing I have learned so far in this wonderful exp of growing your own is nobody has a magic wand to wave at the other end of your internet connection
If you are unable to give up this info then I (and most others who dont guess) wont be able to help with your problem. Lastly if you have no clue about the things I just asked you will have better luck dropping a seed at the window into the backyard and crossing your fingers. :wtf: By no way shape or form am I trying to be mean or cruel just talking straight forward and honest :jointsmile:

Ok lights and temp look real good. PH on the other hand, 6.5 is the highest you really want to go. 5.5-6.2 is average. Take a sample of your water to someplace like Petco to have it tested and it is free! They should be able to tell you what the water is like when it comes out the tap. PPM's and PH are the main 2. Also do you use Calmag by chance?? Lastly a pic or 2 would be great.

What should "PPM" be??? in "Veg" it is @ 950-1050 ppm..well send pics soon.....Thanks again for your reply:thumbsup:

I think that's kinda high... especially for young plants. Try to stay around the 600 ppm area.

i fill ebb/flo with @ 2"of hydrotron on bottom, then "rockwool"....How many times should it be watered a day????:wtf:

Thank you all in ADVANCE:thumbsup:

Back when I was using RW cubes and blocks I watered mine 5 times a day at 15 mins each. You could prob start at 4 and see how things go as to many variables to list. Guessing at their age by looks I would say not over 800. That yellowing really looks like a PH issue. Next time it floods lift liner up some to verify those 2 buckets are in fact flooding and not a clogged line from roots, etc. When you go to put liner back down in bucket do it CARFULLY and SLOWLY or you will have wet feet :whalephant:
