Thanks for adding this. I think we figured out through the thread that I screwed myself by tinkering with the feeding schedule. I definitely shocked the plants early in life with 500 ppm immediately after seedling. I was also drastically under-feeding calcium/magnesium because I use pure...

It's the nutrients, specifically the Micro is known to cause this, I check every single day for contamination. I'm actually a microbiologist. I am using Beneficial bacteria from a canadian company but I'm about to switch to Great White for the next bucket and onward.

the rockwool is only in play at the very beginning, the rockwool gets nowhere near the water at any point, there's no fear of overwatering. it's not sitting in water. my roots touch the bottom of a 5 gallon bucket while sitting in a typical 5 gallon lid net cup/pot. seems like a pretty common...

Here are the roots recently. The brown staining is from the GH trio (this is a common effect I've read) and also the beneficial bacteria seems to be concentrated mostly at the top. There is absolutely no smell, no scum,no slime, no dead roots, no diseased anything that I can detect. I have...

do you think my plants look ready for lucas formula? I mean I have the stuff on hand! Do you do 8/16 or 5/10? I read the updated guides that talk about the difference in light, some said 400W+ but I think that applies to HPS. My LED is 240 Watt and can replace 400W (supposedly) HPS so I...

Not helpful for what I am asking but thanks for coming out.

Man, I appreciate you trying to help but this is pretty far off from what I am asking about..... I really am not asking about any of this and confused why you are adding this information to this thread. Please keep on topic.

I grew them in rockwool for 2 weeks then placed the rockwool in pH'd hydroton like literally every guide I've ever read. I gave so much information, this is completely out of left field for what I am asking for help with. I know that putting 500 ppm water for seedlings is bad now.

I started using this since it seemed reasonable. The issue is that I reduced CaliMagic to 50% of recommendation EVEN ON THIS FEEDING CHART. So where it says 1 tsp CaliMagic to start off with, I was using 1/2 tsp CaliMagic by mistake. I then learned from these very comments that the conversion...

Do you use tap water? If so, our situations aren't comparable. Define 'proper mix of nutes'. For example, the strength of the light you own can change the nutrient concentrations that you use... I am providing a lot of info here so that people can address my situation correctly. Looking for...

I'm using the recommended dosage on the bottle? 1 mL per Litre. EDIT: Ok. Your comment just made me do some math. This might be stupidity on the part of GH and not myself. So, on the Canadian bottle, it tells you 1 mL per litre. On the american bottle, it tells you 1 tsp per gallon. If...

Thank you so much for finally responding. I think people are scared by the ridiculous amount of detail I gave... but I think I have just been under-feeding. I have more data not added to this post. The EC and ppm are dropping steadily and pH has stabilized but is still slowly dropping (0.1...

Plant 01 and Plant 02 plus the past 2 days of measurements in case someone decides to try to help me.

Hi everyone, First time poster, first time with DWC. I have grown successfully in soil before. I have been completely overwhelmed by the many, many different opinions and techniques available for DWC. I need to reach out directly! Sorry for the long post but I really want to get this...
