Hey guys. I have an Undercurrent RDWC. There are 8, 13 gallon buckets. I just started flowering them about 5 days ago and never had a problem at all until now. My situation is a little different seeing as to how I have 6 1000 W lights over 8 buckets, meaning my plants are BIG, so doing a res/water change is damn near impossible (cant move around those plants). What I usually do is I wait for my plants to drink up as much as they can (usually almost half) and then I top off and add appropriate nutes. My water temps never go above 69, and the lowest they go are 65. Room temps are 70 at night, 85 during the lighting period. RH is always around 20-30%. PH is always 6.1-6.4. PPMs right now are at a little above 800. Last night right before the lights cut out I topped off with water, added nutes (Dutchmaster flower A&B, silica blast, sweet raw, great white) and they looked fine for the most part. I go down there just now and notice that all the new growth on my plants are drooping a bit. I've done searches on droopy plants and seen other people post up pictures of REALLY droopy plants, but mine aren't THAT bad, just don't want them to get worse. I can take pictures if needed. I've done lots of reading on what causes droopy plants in a DWC and most people say its from plants going into shock because of Calmag deficiency,high PPMs or too high/low PH, but mine always seems stable. Should I be worried? Is this normal? I just don't want them to get worse. I will post pictures later tonight to show you what they look like. Thanks.
