After posting questions and pics in other growers journals I decided I should have my own.
Setup:
3' x 4'x 4' room
Lights -
2x 300w Viparspectra LED
1x 600w Viparspectra LED
2x 70 HPS
Using General Hydroponics Nutrient System
Started plants on 10/31/17
Tried out manifold technique for first time and it really slowed things down for a while there. Followed tutorial pretty closely so maybe to be expected.
Growing as a SCROG so manifold benefits aren't that strong, but it gave me a better sense of how to prune/shape them for the next grow so I think the experiment was well worth it.
Switched to 12/12 on 1/5/18 so Day 19 for flower.
(Actually running 11/13 hours and have been glad to have the 1 hour extra when my work in the room runs late - + 2:00 am.)
Plants:
2x Skunk #1
Jack Herer
Lithium OG Kush
AK 47
White Widow auto
The white widow started to foxtail a while ago and I think it was from keeping it on the early and middle bloom feed schedule too long. Running a lean late bloom schedule for it now and actually pinched off the tops of a few of the buds and they seem to be filling out more now. I could say a lot about that little plant... But it's not really my focus.
Right now the runoff is reading around 5-5.3 for everyone except the Herer, which is at 6.0.
Temps have been great lately at 76-78 degrees day and night. I have a heater in the room so it keeps the temps even. Though last few days it has been dipping into the upper 60's at night which I was stoked about. Checked today though and day time had sprung up to 86 degrees. Why the shift, who knows? My lung room is adjacent and since it's a basement grow that room (big closet really) tends to stay cold but it might be varying enough with the weather to cause the fluctuations. Dialed down the thermostat just a hair and will see how it looks tomorrow.
The heater has a cardboard trough it blows through to keep the air off the pots until it mixes with a fan stream at the back of the room. Works well.
Humidity as been between 39-45% or so. Happy with conditions overall!
Defoliated on 1/24 but was a touch conservative on it as I think I have over done it in the past. I've seen some amazing grows here that seem to have a dense canopy. Plus, the low height of the room means I'm keeping the plants real low so it's more of a carpet canopy.
Started noticing some Mg deficiency in the Herer two days ago. Checking the pH chart I see that above 5.5 starts to cause a drop in Mg uptake. **slaps his forehead** I've been trying to raise the pH... So, tomorrow I start trying to lower it I guess.
Symptoms are in center of room which has a crazy light exposure. Reading around 900-100 micromoles. I know that's high but, 1. I can't raise the light, and 2. I need that intensity for the rest of the room. I'm going to make a shade cloth canopy for the center of the room to tone that down a bit. I suspect the Mg problem is showing more since the plants are a little stressed from the light in that area.
I'd point out which plant is which in the photos but it's hard for me to tell since I have trained some stems far from the pots and they interweave. When I want to check, it takes me a couple of minutes to trace a bud back to it's source. Easiest one is AK 47 front left.
AK 47 is paler than the rest of the room and I thought it just needed more feeding. But it's showing a touch of tip burn (like the rest of the room) so maybe it's more phenotypic. Not sure, but it seems to be doing well in any case.
