Hello, I'm not sure how to approach this because I am completely stumped. My plants looked very healthy the whole grow with the exception of some small rust colored spots on some of the lower leaves at about 5-6 weeks 12/12. But the flowers turned out really strange. At first I thought it was because my light (600w digi)was dimmed to 50% for a couple weeks. So, I was willing to accept that and move on, but, I've got some more that are 5 weeks in and have been under 600 the whole time and they've got the same thing going on. Here's a rundown:
Strain: Blackberry Kush, I know it's not genetics b/c I yielded 1+ per straight from rooted clones in perlite / vermiculite mix jrosek style with floronova and no supplements other than a couple foliars of sonic bloom.
Medium: straight atami coco, this is my first time flowering with coco and I decided to use straight because well, I'm lazy and was really trying to avoid mixing anything and I plan to just put the used coco on the lawn and really didn't wante to have perlite in my yard and it seems like plenty of people do it but from now on I'll add the chips to the mix in case this was the problem. They are in 24x36x8 masonry tubs with "better than rocks" at the bottom for drainage.
Food: peters professional hydroponic formula at about 3grams/gallon plus about 1.5 grams of calcium nitrate and drip clean. Drip fed through Tropf Blumats. Basically, they are set to keep the medium moist and I had no runoff but again there were no apparent deficiencies or over feeding. Leaves were nice and green to the end.
Light: 600 watt hps (sunmaster) with lgm 5 led bars around the edges. Oddly enough, the plants under the leds look a little more normal - I attributed this at first to the hps being dimmed but this seems to be the case in the new batch as well so I think that this must be a combination of the light (or heat from it) and some other factor.
Environment: This is where I'm fuzzy, and it might be my biggest problem. Because of all the wet coco the humidity in the tent is pretty high, the only hygrometer I have in there is right on the coco and it stays around 70%, the outside room is 50-55% but in past grows in the same tent I've run high rh and been able to avoid mold by haveing lots of air movement and I don't have to deal with the heat from the dehumidifier. Here's the next thing, the canopy temps stay around 80-85 and CO2 is at 1200 but the injector almost never comes on so maybe the sensor's not calibrated right but again, the other grow had no co2 and no one was ever home, this time there's almost always people around and I'm in the room a lot reading and what not.
So, without further adieu, here are some pics, and I'll open it up to discussion. The buds are covered with resin, huge swolen calyxes with an amazing taste and they burn super clean. Almost too clean considering there was no flush. Maybe the problem is that they were hungry but they sure didn't show it. I was really hoping to set up a system where I could constantly be rotating babies into the system and feeding them off the same rez. Oh well, back to the drawing board I guess. The one that is really thin is dried out, that's what I smoked. The really funky looking thing was coming out of the top of a plant that was right under the light. In this thread, post 281 I believe https://www.icmag.com/ic/showthread.php?t=111046&page=44 you can see the whole setup as well as shots of these girls right after I caught the dimmed light. ANother note, some of the tops did purple up a little which I attributed to phosphorous lockout from being too close to the lights, I guess that's possibly my problem but the others I mentioned were right up to the lights too so maybe that's not the problem???? I really want to keep trying this system b/c of all the thought and work I put into it but . . . I guess my first step should be to switch this res to floronova for now.
