Yeah I think this is what’s behind that one branch that looks unblemished in the shade. PH is likely off and intense light has exacerbated (dare I say illuminated) the issue. Dialed it back to 450 PPFD until I can stabilize her…then I’ll prob start slowly increasing it again and screw something...

Not yet. I watered them yesterday morning so I have to wait until Fri or Sat to soak them and check runoff. I did check the soil ph with the 3-in-1 ph/moisture/light meter and it clocked in between 7 and 8. Not sure how accurate the meter is, though, as it was also a $10 special. I ordered the...

Done. Thank you! So does anyone here ever push it to 700 without CO2?

Ok well they were actually around 680 so I dropped them to 600. Curious what others think about this. You can see from pics this morning they seem to be praying/enjoying the light? At least I don’t see any burn or canoeing on the newest growth, but please correct me if you see otherwise. The...

I'm on 18/6. I've been following Jorge Cervantes grow bible...I think he recommends 700 after 4/5 weeks in veg. What would you recommend?

Low ph is the story of my life. :wall: Got any recs for quality PH meters? I think I’m ready to invest in a meter that won’t give me a headache every time I try to grow a plant…

I did have to ph adjust the reservoirs before I left so it’s possible those settled to a different number after I left. My tap water drops from 8.8 to 7.5 ish after a day so it’s possible I downed them to 6.5 and a day later they dropped to 5.5 or lower. I never checked their ph when I returned...

It’s the yellow cheapo meter. I should def recalibrate.

I will check it next watering. Thank you!

This is good to know - thanks for sharing!

Thanks @Budzbuddha! I like your idea to top dress with more FFOF. Sounds like you're leaning towards overwatering and thus a nute deficiency issue caused by leaching, is that right? It's worth mentioning that (if it is overwatering) it might not be quantity-based but more so frequency-based. I...

Wow that's super interesting. I just watered them this morning so will give them a few days before checking the run-off. I was running into weird issues like this last spring until someone in this forum suggested that the molasses I was adding to my waterings was lowering the ph...so I decided...

Right out of the tap it's just under 9, but after sitting out for a day to burn of the chlorine it settles somewhere in the 7.5 - 8 range. I occasionally use Bloom City's Clean Kelp to lower the ph but most of the time I'm using this organic crystal-looking stuff.

Yeah just water so far. I use Down To Earth 4-4-4 during veg and then their 4-8-4 during flower.

Those were old pics, FYI...but I do wonder if the plants were not getting enough water with the Blumats and I interpreted that as overwatering...so I continued to under water them for a few weeks and that's why the browning of the tips has persisted?

Conversely, could this possibly be nutrient burn from FFOF? I did add worm castings to FFOF before I transplanted them back in mid/late Dec...

O Oh sorry I misread your first reply. Is 6.2 better for soil? I can def aim for that - I have to lower it every time anyway. RH is usually around 60 - 65. It did drop down to the 30s for most of the vacation duration since my humidifier ran out of water after a couple days. I guess I've been...

Also for more visual context, here are pics of them before I went on vacation (Dec 19) and after I had returned (Jan 4)
