The last few days I had 3 plants start not looking so hot. The 3 pictures are the 3 plants when I got home today. I haven't really encountered deficiencies, if it's even that. I'm watering at 5.8 and last I checked the runoff a 2 days ago it was 6.8. Any ideas?

Hello ! After I check you ec/ppm level I can't really say that you've using an aggressive nuts schedule as 1.3 Ec is good for 34 days old vegings plants, if you give them plain water every 3 watering then it is perfect and if not then flush your medium just a bit. I bet your issue is mostly due to the tap water vs distilled water: which one is leading to the issue ? I would bet on the distilled water as the level of cal mag is 0 in it. I bet you've got a cal mag issue leading to others deficiencies. Concerning your PH fluctuation I can't actually tell you why your PH is rising but I can tell you that coco is a bad buffer so it can make Ec change while the plant are sucking nutrients , in my case (Blue dream) the Ec was going down every time until I start using organics nuts. PS : I know that Ghe floraseries often making PH rise in hydro so I bet the same is happening to you in coco. Hope it will help you :grin::+1:

Hi @Kaboose13! Well, you're having a nutrients-lockout. You over-fed your babies during the last weeks, and as a result you're having salts-buildup in your medium. In this scenario I would flush the medium with 50% of the container's capacity with a very light solution (at least half of what you've been giving last week, EC ~0.5), then put a tiny fan blowing onto the containers to help them dry / prevent from overwatering. The only way to get rid of those old nutrients is to flush them away with a decent amount of water. Hope this will help, keep us up-to-date and happy growing :facepunch:
