Trying to fix deficiencies this week. Mag then cal then phosphorus its been crazy. Dli reduced to 32 this week I think the blue in this light is asking for more magnesium and then causing problems with antagonistic elements to lock out subsequently. Ppms were up to 1090 by day 35. They really are hungry. Learned a lot this week. Tried to stay in VPD ranges as usual but I'm sure this is not true "vpd" either. Anyways she's starting to flower now, her tops are starting to bud.
Not sure if I have light stress, nute issues? growth rates are defined explosive, leaves large and green. I hit 36 DLI one day in the most recent week and I felt like they weren't ready. Temps 84f humidity 72%. Ppm 400-450 ish. DLI 30 usually.
hi there you have root issues actually, that's because the humidity was trapped in the medium so some mold developped, you need a stricter wet dry cycle for this plant, sometimes it recovers by itself but sometimes you also need to add enzymes, humic acid or beneficial bacteria to fix it. Hope this helps ! 🚀
@theplantdaddy, depends if you want biological or not, but if you're in perlite which is sterile then h2O2 will work just fine (and probably better) , just dilute it correctly otherwise it's game over.
@theplantdaddy, no no, just plain water, you can add Rhizotonic or something like kelp extract -based but that's not every time you spray, think every 7 to 10 days.
This week had a lot of difficulties, I changed a lot of variables too quickly and basically my environment was all over the place. Humidity was low, light levels did not get increased. I was mostly trying to figure out my ppms and what looked like a deficiency to me due to lockout. They were foliar sprayed with magnesium sulfate once on day 27 at 100 ppm and 28 at 180 ppm. I'm not 100% sure if it solved the problem. I do see improvement but let's see if they hiccup too long. Hope not. Temps were 78-90 humidity mad swings from 50-81, obviously not all the time but it was a very inconsistent environment, out of vpd. On day 29 I made a fresh batch of nutes and made sure to dissolve it completely and let it sit for a couple mins and mixed them vigorously. I don't know for sure but they look a whole lot better. I took out the deficient leaves cause they were messing with my ability to tell whether or not the problem is progressing. Ppm at the end of the week 750. I noticed runoff was consistently 300 ppm lower than input which is interesting. Maybe they were just hungry and my feed contains a lot of N so it was starting to burn the tips so I backed off. Maybe I was just underfeeding? It was probably everything.
