Ok so I have been posting quite a bit lately but with certain questions and stuff but this post is the one that really needs answers. Since I have started growing about 3-4 years ago, I have the same issue no matter what I do. I get the bigger fan leaves that start “dying” if you will towards the end of veg. By mid flower my plants look miserable. I have done everything that I know of.
Originally I was just growing in FF in 3 gallon buckets and using tap water. This would happen.
then I started using PH pens.Then EC pens. Then I Got a different strain, added cal mag. Changed nutes, changed soils. It doesn’t matter.
my last hypothesis was that my light (which is a HLG 550 clone that puts out 480 watts at the wall with lm301c diodes, was burning my plants. Well I have kept the light at 32” and 80%on the dimmer. And just in case these adjustments weren’t enough, I’ve added 2 exhales C02 bags so the plants can photosynthesize more if needed. The plants are growing great, but the fan leaves are once again starting to show the usual signs. My temp and humidity is perfect with temps in the mid 70s and humidity between 55-70%. I also went from tap waterto R/O water. I worried maybe my citytap At 480ppm (sucks I know) was hurting the plant especially with added chloramine. It doesn’t appear that this issue occurs from the lower leaves to top or vice versa. It appears mostly random. Of course that makes you lean toward a possible PH issue but my PH is 6.6 going in and 6.7 coming out. I would certainly say I’m not discouraged, but I’m aggravated.My plants are growing amazing and the one northern lights I’m running has taken off like no other plant I’ve grown yet and really want it to not be ravaged by whatever is happening. My ONLY current working hypothesis is I got water on the leaves somehow and burnt them. But I don’t believe that to be the case but then again if I believed I knew the cause I would not be here asking.
