Dwc nutrient issue?

Smerkabewl said:
Overall, do you believe I am having nitrogen toxicity issues? If so how would I go about that being that I am in week 6 of veg and plan to flip at week 8? I can try another 24 hours flush if needed, that process takes some time though due to my RO water coming out at a slow pace

No, skip any flush at this point. I do not believe you are having N tox problems right now.
Keep in mind that most nutrient issues do not show "repair" in effected leaves (other then low N).

Your new growth sounds just right.. If it makes you nervous, Simply take a pic of the new growth close up and post it.
I'll take a look and can tell you for sure!

Ah HA! You are doing an RDWC!

Yuppers! 50% of feed charting is about right for RDWC..... Still, use the add back rule for dumping and refilling total amounts as to timing.
Skip the 33% part,,,unless you get advanced signs of N tox (you shouldn't - not at 50%).

There is something about the recirculating part that reduces the needed concentrations of nutrients used.....

towards the bottom, pretty straight forward. just need the labels off each bottle and how much you use:

He IS in and RDWC set up!

50% is where I would start nute concentrations. I would go from there.
He started at 100% and I bet that was an N issue, just starting, and good catch on his part but, should be fine now

Thank you for all your help!

I've decided I am going to try a normal dwc set up due to the fact that I checked ppm of all 4 toward and they were all way over the place by a alot. It seems all 4 plants are in different states of health so I'm gonna separate them to be able to focus on them individually.

My clones should so sex soon so hopefully I can take some males out and things should be easier

Hopefully all goes well! First grow has me tweaking about alot appreciate it though
 
DR Who,Just a question- if superthrive is snake oil, then CloneX liquid is also? Both contain the same ingredient- B1, I have seen a number of positive and negative comments made about superthrive- you need B1 to gain root in a cloner,and after to prevent shock if you go to soil..so what am I missing?Superthrive is nothing more then B1, and clonex liquid is nothing more than B1 with some nutes....If I wrong please show me where?
