Whats good DGC?
Quick breakdown of my grow
Frequency Shift (Irie genetics)
Week 6 (Day 39)
2×4 Tent
HLG 350
Eearthbox
Buildasil 3.0 soil (living soil)
VPD 1.3-1.6
Temp: 72-76
Humidity: 45-50
I’m running buildasoils schedule for nutrients. I attached copy of the schedule in photos.
I have had an issue with yellowing of my top leaves. It’s spreading slowly. I noticed it started about a week to 10 days ago. I’m thinking it may be too much light due to the leaves turning away from the light. I maxed out my distance and turned down the lights 10% two days prior to the posted pictures. I’m growing Frequencyv shift from irie genetics. The website states that it is a heavy feeder so I’m concerned I might be deficient in something as well. Whats everyone thinking may be the issue?
Thanks for all the help through myb grows DGC!

I had a similar problem with my current grow of autos about 2 weeks into flower. As I normally grow photos, I was confused because nitrogen deficiency usually starts at the bottom and spreads up, and the other option for intervienal chlorosis is Mg deficiency. But I was almost certain that wasn’t the case as the organic fert/tea I’m using has Mg in it. So I doubled the fert rate (I was already using half of the lowest recommended “bloom” dosage) and applied Optic Foliar Transport, Rev and Watts a few times and it greened up again pretty good. I don’t want to see fade until there’s only a few weeks left. I think it’s possible autos might exhibit nitrogen deficiency differently than photos.

Sorry I forgot to specify this is week 6 since flip to 12/12. This is a feminized photoperiod.

Looks like more of a watering issue. Back off the watering and light a bit and see if they perk up after a few days of not watering.

The photos are taken 5 days after top watering with 1 gal with buildabloom. I was thinking this may be the issue but didn’t see improvement so I just bottom watered with 2 gals today. I should’ve waited a little longer. She’s usually drinking the 2 gals from the bottom in 2 days. I always give it at least 12-24hrs from resevoir drying out to top water with some nutes or refilling thecresevoir. I figured 5 days from a top water would show some improvement. This is my 4th run only so I’m still learning. Thanks for the input.

I forgot to mention i did not reduce light intensity until 2 days ago. 3 days from last water.

Here me out, reduce your lighting intensity and it will darken back up in a couple of days.

I would check your ppfd, since that is the only number you didnt really give. Did it ever get dry on you once to where it was droopy?
