I messed up...pls help

[Cyph3r]

So this is my second auto flowers run. First one was with no knowledge using miracle gro. I got a decent harvest but the bids were light and airy. They hit hard and have good taste so I'm happy nonetheless.

For my second run I decided to use nutes, pH my water, just do it right. Well everything was going good till I started seeing a lot of lower fan leaves yellowing. I felt like I was leaking in N so I upped my dosage to approximately half the recommended dosage from the company which is general hydro micro, Flora and veg. I water at pH of 5.8 to 6.0 in soilless (root farm) in fabric pots. I have plenty of light in the form of LEDs with temps around around 77° and humidity 55% to 65%. Now in my haste I think I have now nute burned some plants. I think perhaps my issue was letting the root farm soilless dry out too much between waterings. So not realizing that the plants lacked N because of low water I increased the dose and now I think I've really messed things up. Before I go any further could someone look at these pics and tell me what's up. I have 3 Bruce banners, 2 blueberry and 2 dwarf skunks I believe (mystery seeds).

ppp &

Please post this information over in the infirmary. It looks like a PH lock out to me but it can be many things combined?

Please fill in this form: (copy and paste part is below, this first one tells what specifically to include)

-Problem: (brief description)
-Medium/grow method: soil; soilless-- coco, or peat based like Promix, etc. (please provide the actual product name); DWC, NFT, etc.
-Feed and supplements used: include brand, dosage/strength, frequency of feeding and watering (alone); method-- by hand, drippers, rercirc' or drain-to-waste,... N-P-K #'s too if you can!
-Water source: RO/DI; tap- dechlorinated-?..... EC or TDS reading; pH (don't bother with this on RO/DI, do bother with TDS/EC though to confirm it's working well enough)
-Strain and age
-Climate: night and day ambient T and RH%; res' temperatures; any extremes in T/RH% exposure
- Light used: HID, LED, COB, combo of,... wattage; light cycle hours (20/4, 18/6 , etc.); distance to tops....
-Additional info: How long have the plants been affected?...How fast did symptoms appear?... Anything else you think might be relevant..

--Pictures including WHOLE PLANT PICS, and troubled leaves.. use normal 5000K light or flash as other light sources ruin color rendering, critical for diagnostics!

Growing in soilless pH and ppm of both your feed and runoff are needed.
Are you running the coco blend or the pete?

This is the root farm soil I'm using: https://www.rootfarm.ca/products/hydro-garden-potting-mix/

I unfortunately don't have a PPM meter, I've been ph'ing the water to 5.8-6.0 after nutes.
I started a new thread as recommended in the infirmary: Infirmary Thread I added as much information as I could. I believe my issue is under watering. I think because I was letting it dry out too much not only was the plants not absorbing nutrients when the medium was dry, but also I was getting to much run off due to the clumping of the dried medium....This is only my second run so I'm still very new to this
