Can anyone identify this problem? During my SCROG grow, my plant split and soon after some of the leaves started to look like they were burnt. This seemed to be located to just a section of the plant. It now looks like it is spreading but the flowering looks okay. Is there something I should do or is is too late? Also in the pass couple weeks many leaves have dropped from the under canopy. I’m also using the new fertilizer (sold thru this site) and have not had a problem until I started the Bloom phase.
How long ago did that split? Did you repair it at all?
How high and wattage of lights and temps is important to include

The split happened @ 6 weeks ago when I put it under the SCROG net. I didn’t think there was that much strees when I did it. Hmmm, my bad there! I went to 12/12 w/Bloom fert. 4 weeks ago. The WW plant is in soil, 300w LED grow light, humidity has been low @ 35%, there is a fan and an air scrubber also, temps 68°-76°. PH?
I never had this problem when I used the older fertilizer (the liquid concentrate that used to be sold thru this site). Just sayin’.
powder nutrients are usually far stronger than liquid since the bottled stuff is watered down it takes some adjustment I recently switched to GH maxi series it doesn’t take much to raise ppm. A bonus though once you do get dialled in they go far further more bang for your buck

I do understand what root rot is and what fertilizer burn looks like. I one thing I’m puzzled with is, the fan leaves that dropped from the under canopy that looked perfectly healthy without and discoloration. They just dropped off like the plant was shedding. This isn’t my 1st grow but it is the first time growing with the new nutes. Again, Just Sayin’!
