Day 44 - March 25, 2021
Started noticing a couple gnats in our house. It's been warm outside and they are starting to come out. Unfortunately saw some in the room as well and can only assume there are many more feeding on the ladies. Gave foliar spray using Bee Safe Organicide.
Gave all the girls a thorough haircut today and worked on trying to get canopy under control. Vegatation was very thick.
Doesn't look like deficency issue with F7 is spreading. Continuing to watch for any changes indicating the problem is still ongoing.

Day 50 - March 31, 2021
Deficiency Issues:
Still having issues with what looks like Zinc deficiency. Also found 4 of 5 fan leaves with Calcium deficiency over the last couple of days. Runoff is PH 5.8 and EC is 0.78. EC in runoff has been very low. I'm pretty confident it's not a PH issue at this point. Seems plants are rapidily soaking up the nutrients in the water. I also found 8 or 9 fan leaves with slight nutrient burn a few days ago. Nutrient burn seems to have tapered off and haven't noticed any spreading. Going to try adding an additional watering to the schedule to see what happens. I'm hesitant to mix stronger nutrients due to nutrient burn I started to see earlier this week. At the same time, need to figure out the cause of the nutrient deficiencies. I'm currently using the Light Feeding Schedule from Mills Nutrients (says "light", but is still 2.06 EC including 0.54 EC for water + CalMag) Need to switch to flower soon but need to figure out deficiency issues before the switch.
Defoliation:
* Removed quite a bit of fan leaves suffocating nodes. Girls are 10lbs lighter.
Despite the nutrient issues, the girls have been filling out fast. Did a timelapse over the past couple days and can see significant growth in a short period.

Watering with 5.8/5.9pH, 2.06 EC (Runoff 5.8pH, 0.78 EC)
Few leaves had small nutrient burn on the tips earlier this week. Nutrient burn appears to have tapered off.
@GuerrillaNo_4, Thanks! This is my first grow in about 9-years now. I grew for a couple years previously. Cut a lot of corners back then though and caused myself a lot of headaches lol Trying to be proactive this time around and maintain a bit more control on all the variables.
@greenthumbartisan, im presently in my first hydro grow and am using a torus hydro perfect ph balancer drop in and I haven’t had to adjust ph AT ALL as of this point. Might be due to large res with single plant but they make an inline version as well you might want to look into and could still add to your system at this stage. Was skeptical of their claims and am still in veg but appears to be working! Your plants looks great!
@TheCode, Gotcha, yea I've saw quite a few designs using PVC and scrog on youtube. I also saw a video on one Mr Canucks channel and grabbed the scrog nets he used. (found size that worked perfect for my setup) From there just played around with PVC pips to build a proof of concept for my needs and once I had the measurements down, I built 8x of them. Like 10 years ago I tried growing under 6x 600 watt bulbs and grew some pretty big trees; however, I spent two months having to army man crawl through the room to do basic maintenance lol. That experience was my biggest motivation to try and build something more modular this time around.
Still a few quirks I'm running into with my setup, but will hopefully get smoother and smoother over time. 2G per watt will definitely be god .
This is my first attempt using LEDs. Been a long time since I've grown, but the tech seems to have come along way since then. So far I've been very impressed. Hoping to see a good harvest them.
As far as the pens, couldn't agree more. For the bloody cost, you would think maintenance would be easy. They're a thorn in the side. Every time I test, there's always the thought in the back of my mind, is this thing even accurate? lol
Would be nice to not have to worry about pH (feels like its the bulk of the work)
Good luck with your goal! hope you hit that 2G/w bar
@greenthumbartisan, Well especialy for newbies when they start this hobby all ph things can look difficult I mean knowing what pen to buy how to keep it working it looks the TDS meter is much easier to maintain and use because it's simple device, but with ph pen it lil bit annoying lol for me i change those cheap pens every year ,every new grow try to calibrate it and when im using it and finish using it put it in distilated water take it out and just put the cap back so idk cant really keep it really nice i dont have a fckn laboratory it;s little bit annoying .
