Ok, so this is my 2nd grow and I am running 3 barneys farm pineapple chunk clones that I took from a pheno I selected from the 1st run. It is currently week 9 of flower. I have 3 of them in 7 gal smart pots. FFOF and feeding with FF dirty dozen plus kelp me kelp you and holy mackerel. They are in a sealed 4x10 tent powered by 2 spider farmer sf2000 and 1 sf4000. The temp stay typically between 75-80 during the day and then drop to around 70 at night. And my rh is kept between 45-55%.
Ok, so now that is out of the way. I ran into this issue at the end of my last grow and then about half way through this one about 2 weeks before I switched it to flower. What happens is the GREEN leaves start to get brown spots, on the top and if you flip them over there is a whitish discoloration in the same location on the leaves as the brown spots on the other side. The fan leaves do too. What happens is the leaves eventually turn yellow starting at the tips, and then once it gets about half way up the leaves it turns to a redish/brown and the leaves dry up. I have included pictures.
What I HAVE TRIED and KNOW. ok so initially When I saw the brown spot I thought cal deficiency. However thats what i thought when this happened last grow and since then i have added calmag on every reg watering and thats how these 3 have ran their entire grow. So I doubt deficiency. Then when I saw the white discoloration on the under side of the leaves I thought pests. It wasn't mold or anything as it wouldn't rub off. Not to mention the rh is well controlled and I have ALOT of fans so circulation isn't an issue what so ever. Not to mention there wasn't any pests flying around or crawling in my soil. What it kind of looked like is the brown dots on the top of the leaf burned through to the bottom but left a white spot instead of a brown one. Still though, I sprayed with neem oil on a 5 day treatment plan. (Still in veg) I also mixed in diatomaceous earth into the top soil and put up stickies. Never saw any kind of pest stuck to those. (I keep a clean grow room)
What I also did at the same time thinking POSSIBLY the soil ph was off or I had salt buildup from the liquid nutrient, was flushed the plants with water ph @ 6.5, and then gave then I light feeding after words.
After that the brown spots that were appearing on the green leaves and producing the weird white mark on the underside of the leaves has stopped. So I think it was some sort of nutrient issue but I have no clue which. I follow the ff dirty dozen feeding schedule along with their flush schedule. I f,-,-,w,-,-,f and so on. So I can't imagine there is alot of buildup especially bc I use my qet vac to get out all the run off.
Anyway, i waited 2 weeks and started flowering.
No new white/brown spots. Now any leaf that had ANY of the brown spots slowly wilts from the tip and then turns this weird rust color. I don't think it's rust mold. Again bc I keep a controlled and clean space. Plus it doesn't actually rub off of the leaves. It just creeps up the fan leaves and once it reaches where the stem connects inside the bud the leaf just dries up and falls off.
I have included as many pics as I could. A couple show the late stage "rust discoloration" and one shows what the little white spots/brown spots that appeared on the tops/bottoms of the leaves look like. This pic is just of a small blade as all the fan leaves are gone but every blade on the big fan leaves had these spots too. Another pic that shows the yellow color the leaves turn before turning the rust color. As well as one that tries to give an idea to just how wide spread the issue is. It's on literally every branch.
I know my harvest is like 2 weeks away so I'm not too worried about this harvest. However it happened on my last one too and surely it strains the plants and is affecting my yield. I would like to solve this issue incase it starts on my next run so I know how to be proactive. Also as a note I have a really nice EC/PPM/Ph meter and I am REALLY careful about checking the ph. It is ALWAYS between 6.35-6.50. So yea. Any suggestions would really help. I've tried other sites but no one seems to know what it is or how to be proactive to keep it from happening. Really appreciate it.
Thanks mates!
