Whatz up everybody?
So my last few grows ive noticed this is always the first leaf damage i see. These clones are about two months old. Very healthy up til now. Just started to LST and supercrop. They still are once I resolve this. 65 starting ppm so I add 4 ml of calimagic per gAllon of water. I adjust my ph to 6-6.2 and water daily until I get a good run off. I am growing in rockwool minicubes. I have not flusbed because I water daily and get a good runoff so didn't think it would,get a salt buildup. What does this look like to you guys? The start of calcium or magnesium deficiency or salt buildup? I'm really not sure so any advice would be great.
The last picture of the weird leaf I don't usually get though.
Thanks
