I have a few theories honestly I've made my share of mistakes on this grow. This is what I think they are:
Nutrients:
Going into the grow I didn't have the girls on good food just some promix organic based stuff I had kicking around as I finished off my other nutes. You remember the light stress of first being in the room I felt was partially due to poor nutrition/soil root conditions. I saw an old post from Renfro saying if the soil Ph is fucked the girls can't eat right once they're re in strong light.
second fuck up with nutrients is that I first started at half strength things were good, then I started to get more confident and got up to the strength floraflex was recommending to feed. I know better I should have been feeding, checking run off to make sure they eat it especially when starting with the new food and having those problems at the start in veg.
I kept feeding @1400 for a good while and the ppm in the run off was 1000-3000Kppm on some pots. So I flushed everything down to 600-800ppm and just kept watering at 800 and then water next watering alternating for the rest.
Growing media : I normally use promix HP. But I was originally gonna try organic growing with amendments. I bought like 10 bails this promix BX with extra bacteria. I did a few runs tried organic growing and didn't like it. But had all this soil which I used. I found when I would drench it would hold the water forever. But if I water somewhat light runoff the pots would dry as fuck by the next day. I feel like my girls were suffering some weird over watered under watered stress. Then when I started flushing ( when I found the PPM to be high)I felt like they were getting overwatered cuz the pots were staying sooooaked
VPD
For a good while I was running the two Dehus during lights on. I found the lights and AC alone would maintain humidity too low. The girls gave off a lot more humidty during the stretch then now. So the VPD was pretty drastic and I got what I believe to be calcium related lock out. . The dehus were reading different ambient room humidty so they were working when they shouldn't be. I removed one dehumidifer. And the other is on a timer to only come on at dark. But right now I should be adding a humidifier to keep my humidty up. Currently it's 45-55 which I've done with no problems before. But I believe it could have contributed a factor running at 2.0VPd with high intensity and shitty PH and over feeding stress. As a combo could have been too much.
so for next cycle I have a bunch of changes to make. I will be hanging the dehumidifer up above and use the two 12" inline fans to force air down into the grow for better humidity and temperature mixing. I will consider adding some humidifiers though I think I can find a better balance with plant count and using AC for day and dehu on night sched. For nutrient next cycle will check my run off the first few weeks no question LOL. I will run 1 mom per tray for 4 trays. This will be 1 plant to water. I got 4 plants big enough to do this. So timing sill be good. Then I hope to trial a drip irrigation system on two of the trays and hopefully will use a hydroponic medium something like coco and perlite or perlite and vermiculite. Currently getting much help from some helpful forum members (
@2com ) on setting up a top drip system.
the sandstorm should be ready @ end of week 8. Already showing some amber trichs. Everything else I will take as it comes ready. Sensi star and skittles usually need 9 weeks. Most should take 9. But the Pk usually takes 10 sometimes. I dropped the night temps down to 73. And will keep getting colder from here out to help them finish.
so yes I'll leave them a couple weeks still.
Cleaned up some of the clones for next round. Think I'll just run LA Kush Cake and Amnesia for the little babies.

picked up some seeds cuz they were cheap and been after the pineapple chunk even though my buddy told me BF is no good anymore. Lol. I saw lots of great pineapple chunk grows. And the DP seeds were cheap AF and I like fruity strains sooo yaaa. Pineapple chunk and Critical Orange Punch. They gave me a free auto seed.Such luck haha.
