My ppms have been rather low around 425-450. Im about to do a water change and I will boost that up more towards 600. The picture I attached here should give you a good indication. I believe now that it has something to do with me spraying with h202, I also used humic acid in the mix and I realized that was dumb. I think my leafs need to be sprayed with fresh water and rinsh them off from multiple sprays of h202. That combined with perhaps hotspots and the small area of my tent has effected the leafs. Does that make sense? Some of the tips of my leafs are burnt as well. And this has only gotten worse the last 24 hrs so I believe it to be that and im going to freshly spray my plants. Hopefully things look better then as I believe they will, but I still have the issue with the leafs curling upward from one of my previously pictures. You mentioning the VPR ratio and it potentially being at a deficit sounded right on, especially sense it says that it mimics a Mag-Def. Which I thought this was from the beginning. Ill see how things look after a fresh spray. Im also putting a new oscilatting fan over my canopy to ensure there are no hotspots. That leaves the VPR like I just said but it seems like I am within the right ratio at 73 and 42-45 humidity. Ive never had these issues and that's why I thought a lot of this had to do with the small tent I was using. My rootz literally look amazing. Huge and all white, even my branches look bulky with no discoloration on my main branches and side branches. So I think a fresh spray will help a lot. Let me know if I have valued my VPR at a wrong ratio. If I haven't then all I can really come up with is that I have hotspots, which should go away due to added the oscilating fan over the canopy, or another micronutrient def. SOOOOOOOOOOOOOOOOOOOO FUCKING FRUSTRATING... at day 21 this run had the biggest colas ive ever had at that point. Thought I Was going to hit 2 lbs or something under this 600 watt lol. But analyzing things now I realize I may have overdone it with the h202, and I don't think you can ever use h202 with a humic acid during a folial sprays. Makes complete sense now. Also I am about 12-15 inches away from the canopy, just as something added information. I believe I have been much more complete with my run and the information I have provided here. Ill touch base tomorrow and see what is mentioned. See how things look after I rinse the leafs off right now. Give it 24 hrs and post what has occurred. Im thinking because my root mass is so big and healthy, that ususally will indicate your plants bouncing back at a quicker rate. Your rootz is where everything lies, just don't over fertilize or burn like it seems like I did with h202 and the leafs lol. Im a dumbass and should know better with how professional my setup is and the effort and time I put into it. I scrog the fuck out of my shit like no other all top buds and lollipop. OOOPS I mean more like super lollypop. 100 top budz one fucking plant. Im not fucking around when it comes to my techniques and my approach and work ethic. I stop at nothing to ensure everything is addressed. But all it takes is one fucking thing to be off and everything can be a mess and waste of time. REAL TALK.
