So I'm on my third crop in DWC and I seem to be encountering the same problems over and over. Now set aside that up to this point I've been battling bugs constantly and think I finally have a hold on things. So the problem you ask. Well its like this. My plants are about 7 weeks into flower and haven't really filled out that well. They seem to eat for maybe three days and then my tds stays the same or rises. I can never seem to tell if they are under fed, over feed, or suffering lock out. Example day 43 flower tds is 740 and 6.3 ph. The next day, 44 tds is 560 and 7.2 ph. I add nutes to bring the tds back up to 810 and adjust ph to 6.4. 10 hours later the same day tds is 720 and ph 6.6. The next day, 45 tds is 680 ph 7.0. I bring it back up to 850 and 5.9. Day 46 the tds is still 850 and 6.4 ph. I thin the mix down to 820 and 6.4. Day 47 it remains the same 820 and 6.4. Day 48 the mix goes up 10 tds. I assume their overfed and start with clean water again and try to feed less. Day 48 still, lower tds of 430 and 6.4. Day 49 no change. Now I'm wondering if their not eating because the tds is to low so I up the dose to 690 and 5.9. Day 50 tds 720 and 5.8 ph. I could keep going here but doubt that would help. I've read tons of info on DWC and everyone has their own opinions but nothing solid. I tried the Lucus formula for a bit but those numbers were way to high. My tds has never broken 1000 in flower or 400 veg. I'm looking for someone with some experience with th GH flora series in Dwc who I can see how their feeding. Maybe figure out where I'm going wrong here. Any help would be greatly appreciated.
