Just stunted and burned for the next 2 weeks.
I just worked on the tent setup and stuff while they recovered. Added some white plastic to cover the pots.
Added a surveillance cam with nightvision in the tent so I could check in on the girls when I not home.
Also added a wifi Temp/Humidity monitor and wifi power strip that monitors energy use watts.. These little wifi gadgets help a lot.
Im pretty sure that 300ppm wont burn cannabis plant. I start my seedlings at 350 to 450 without any burn. Near 450 might get some stunth grow if light feeder strain.
@Hattiwatti, Well in my case. In DWC with RO water, it will. I stupidly put my ppms at 400 and it almost killed all my plants. It took them two weeks to recover. I will never do that again. Less is more. The critical strain ended up hermieing on a branch in the back and spread seeds in my tent. Mostly to itself. But I have found a few fat ripe seeds in my other strains. I also had night temps at 55F for a few weeks and a light leak I didn't know about.
Nice grow matey indeed, hydroponics is king, no doubt. Quick question, you stated that you grew 20 years ago, not many autos back then if any, cant remember myself any on CW when I joined in 2001.
In your opinion, can you taste the ruderalis genetics in the Hulkberry? Asking hence I have grown 3 auto strains now and I find that the taste is negatively influenced by it
