Happy to help. ;)Thank you for your reply. I will do as you said immediately. When you say top them. Is that the same as super crop?
Likely a combination of pH issues and possibly starving a bit for nutes. 500ppm is a bit low in high light conditions.My nodes look great. It's the huge fans turning brown and drying out.
Too much air can be a problem. Turn off the pumps for an hour and see if your pH drops. If it does, there's actually too much air going through the solution.My bubbles are ripping.
pH at 6 is too high. Full nutrient uptake happens when pH rises from 5.4 up to 5.8 and then dropped back down to 5.4 using nutrients.ph at 6. Nutes at 500. Actually using RO water so I add cal mag to bring it up to 200. Then nutes as it says brings it to like 350 to 400. I just bumped to 550. I also am using current culture h20 for my nutes. Along with UC roots.
Keeping the 68F stable is massive. Even a few hours of high temps will impact yield.My roots are bright white with green roots coming through the pots. No smell. Just added photosynthesis plus. The plants woke up nicely. But I'm still not out of the woods. Hard to control my water temp. I'm trying. It's at 68 now but I've seen it climb to 73. Ugh. This is all cool as it's a learning experience. My bulb is a hortilux blue 1000 watt. Just swapped out my flowering bulb yellowish as I was told. I'll send a pic of my set up. Please keep the suggestions coming.
This is good advice. Also, keep the same level of nutrient solution, when you add more than before it will waterlog roots which have adapted to being in air.Is the nutrient water level higher than the bottom of the plant baskets? I have found this drowns plants. Keep that water level down and the roots get more oxygen.
15 years experience says this is not good advice. You may have gotten away with it occasionally, but coaching others that it's not an issue is doing them a great disservice. Whether you were aware of it or not, your grow suffered and you lucked out.Back when I did DWC I often had res temps in the 70s and higher. I'd toss in big chunks of ice to help, but didn't have much problem with higher than ideal temps.
Tentatively, I'm leaning toward your plants trying to eat themselves at the previous nutrient level. Having not enough nutes will cause deficiency issues as well. As long as they continue to do better, the low nutrient strength was the main issue at hand.Oh and my plants are doing much better now.
