Hi,
I am having issues with my plants in the flower room. The air temp is around 65, water is 63 degrees. Nutes PPM is at 1050. I have 18 plants under a 1000W lamp on a mover. Nutes were at around 900ppm, but plants were showing signs of Mg deficiency, so I added the low dose of CalMag, which brought the ppm up to 1050. It is a 4" pvc tube system running out of a 55 gallon res.
The issue is my plants are wilting. I'm thinking it's the CaMg I added. I added the recommended heavy dose from the manufacturer. I noticed the whole plants wilting around 2am today. So I drained the res, flushed the system, drained it again and again refilled it with fresh water. I then got the nutes back up around 900ppm, then added the low dose recommended by the manufacturer. Today, while the light was off, the plants came back up and looked pretty good. I was thinking that the problem was fixed. But the lights have been on in there for 2 hours now, and all the plants are wilting over again.
My plan is to once again flush the system and add the nutes back to the 900ppm I usually keep it at, but NOT add any of the CalMag. I'm hoping I can at least get the plants back to the state they were in 2 days ago, then figure out what to do.
What do you think my problem is? Do you agree it would be the addition of the CalMag? I assumed this would fix my plants, but seems to be hurting them. Is there anything else you would recommend I should try or look into?
Thanks in advance,
CB
