day 31 veg
i just topped her so she can get bushier. upped nutes to 450 ppm since it felt like she was growing kinda slow.
near the leaf's center vein there is some abnormal brown & yellow spotting. it's early stage of something but i'm not sure. can't be calmag since i've been feeding that
also, she looks too lime green for me. i've been feeding half myco+ root stim & half GH's floramicro so i don't overfeed nitrogen. should i do full strength of floramicro?

not sure if this early leaf septoria or nute lockout

Where are you getting your feed info from? Are you following directions? I have never used GH but your having nutrient issues. I would guess because your not following the directions so your ratios are all out.
Use the ratios as per directions then dilute it to get the ppm you want. Go by the plant and not so much the weeks as stunting etc needs to be taken into account.
I have never used that root stim so use it as directed.
You want about 200-300ppm max of nutrients I would start at 200 and see. By nutrients I mean only your 3 part nutrients.
Here is what I would do but there is probably a better way.
Take a gallon of RO add the GH nutes in the ratios that are on the directions. Write down how much of each you added. Then test the ppm and simple math will give you what you need to add to your reservoir to get 200-300ppm.
Then start from scratch with your res. Add your cal mag to your RO and then add your calculated nutes to add 200 ppm.
The directions are not something to disregard and the nutrient ratios are there for a reason. The nutrient strength you can change but ratios not so much without knowledge of them

feed info i've been using the GH bottles' labels.
for example, the label calls for 1tsp of one nutrient (max feeding). i use an online calculator to get the ML liquid measurement to use my ML dripper so i can feed it at a 1/4 or 1/2
i'll follow the label's instructions, quarter strength of the label's max feeding. i'll do that for all 3 of GH's main nutes. then ill do calmag full strength & myco+ full strength. the only exception to this method is that i've been doing half strength on floramicro, to not over feed nitrogen.
i recently watered using the same ratio but instead of 1/4 strength i went half strength on the 3 GH nutes. (continuing to use myco+ root stim) i've been watering with barely any RH water runoff. no flushes yet
i think you're right. i don't want nute lockout. maybe i ought to go down to 200.
i followed a guide but you're right about keeping an eye on the plant. this is my first grow so i'm learning as i read different points of view from different sources & go along.
maybe i should cease using the root stimulator & just stick to the main GH nutes so i'm obeying the GH nute's feeding label

day 41 veg pic
10 1/2 inch tall
top leaf temps have been around 80f with 55% (playing it safe because it's so warm)
soon upgrading the carbon filter & exhaust fan to 8" + 40" standing oscillating fan.
i soon will be turning on the cob leds when it's already warmer than i'd like

Nice and bushy you can see an ever so slight sign of heat stress but coming along.

day 45 veg
how's she looking from an even cannopy standpoint? i'm not afraid of trying supercropping if LST won't work. the top 2 cola ends are growing consistently...
updates:
got the airflow upgraded
now have a 6" & 8" passive intake, 8" carbon filter & 8" exhaust. huge difference in the noise & airflow compared to the 6" exhaust & just 1 6" passive intake in the 2x4x7 tent. top leaf temps max @ 74f
been trimming large fan leaves to promote air flow & to stop the leaves from sandwiching. was getting condensation in-between leaves

yeah. grow room had some large temp & humidity fluctations. wont be the norm
tried using COBS but it was too much light
i still have the VPD algorithim & am using it.
how is she looking from an even canopy standpoint?

the chart shows the difference in RH & temp

pics taken for a while of lights on. with the new exhaust & way for me to graph the RH & temp, i'll be able to set a schedule on my thermostat. 10 degree F difference from night & day, right? daytime hotter
Yea daytime hotter. You are getting humidity spikes after lights out... You want to get this under control or you will have to lower your overall humidity to compensate. You could try lowering the temps slower at night. nice and even so far

@TacoMac thanks for pushing me to do some research! according to the attached chart, VPD is better at measuring than RH.
source: https://www.alchimiaweb.com/blogen/vapor-pressure-deficit-cannabis-cultivation/
basically, for optimal leaf transpiration i need to be in the green for optimal potential.
i'm not seeing any condensation form on the leaves.
My god, I'm jealous of your high levels of diplomacy AND attention to detail. This was an interesting thread to read through... looking forward to seeing the results of your vigilance!

day 48 veg
the plant leaves are a little lime green
the plant was drooping a lil before i watered her, been doing it every 4 days or so lately with some runoff. i'm 50% perlite so maybe i'm underwatering? she seems to dry out the first few inches in a few days but i can feel humidity past 2 inches so i've been hesitant in watering her more often. i've read in one thread many users echo that coco cannot be over watered?
will need to test runoff here soon
i think i light burned her a lil bit (oops)
i've been using the feed chart, week 3 on loop

day 50 veg
i read that light stress during flower can cause plant stress that can appear as nute deficiency.
i moved the light up from 24 to 28 inches since there's some signs of cal/mag deficiency even though i'm using calmag. also some light bleaching, oops!
she's only 9 inches tall,
super compact node spacing
i've already had to do some pruning so the leaves aren't sandwiching.
i intend to veg her for another 2 weeks then flip her

Really good example of how temp affects humidity. Looking good thoughday 50 veg
