Very new to growing, just got thrown a learning curve - many cracks have appeared on leaves. I'm just growing one plant right now in a 4x4x6'10' under a 1000w MH for veg (overkill, I know, but I had about 14 seeds and only one survived past seedling due to weather conditions outside of the tent (Barney's Farm seeds did not make it - made me cry). This specific plant was from bag seed, fairly sure it's a herm (could be wrong) - but not concerned with that - what I'm also concerned with is the short stature of the plant (it's about a foot and very bushy) that I chalk up to being a highly indica dominant variant. I have the cool tube ballast being pushed through with a 240cfm duct fan & air being pushed out from the top with another 240cfm duct fan. I keep the ambient room temp around 70 degrees while the fans & lights are off (they are on the same timer as the ballast, minus the oscillating temp controlled fan in the tent)
Over the course of the past two weeks there are many cracks forming on leaves - I live in a cold climate during the winter (top of New England), this is grown in a large spare room and I have the light ~3' from the plant. Humidity is low, about 16% during light times and 28% during dark (18-6) which I recently changed over from 24-0 when I noticed the top starting to yellow - also put the light up about a foot and a half because I speculated that it just was too close. Temp's flux from 68 - 86 depending on dark/light (I also have a temp controlled fan that kicks on above 74 & turns off below). I topped it about 3 days ago as the top was looking rather yellow and it was spreading to other leaves - this stopped it in it's tracks.
I use distilled water with the full line of GO's organic nutes, FF Ocean Forest with 35/40% perlite. I notice about 1/2"-1" of growth day to day. Since the topping the leaves are in a bit better condition but still some cracks are forming in/around the center and tips of the leaves, both on fans and branches. I'll post photos in a bit. I was not adding the CalMag nutrient up until a week ago or so, and before that I had been using tap water that was high PH but used PH down on. It's an older house, so I assume the culprit might be crummy water conditions.
I've searched the threads & googled this, but all I see is nutrient problems that turn the leaves brownish, they look very dissimilar to my problems. I've since trimmed off the really badly cracked leaves (some had the crack in the middle of the fans and made them pretty much fall over) and the plant seems to be less angry and cracks have relatively stopped spreading.
Any help would be greatly appreciated! Thank you in advance!
