Oh! And as for VPD get an infra red gun and check your leaf temp. Mines about even most of the time because I can’t raise lights higher. 1 to 1.6 is ok. Aim for 1.4 in flower and lower temps lower humidity like 24c and 50% or lower humidity

Looks like nute burn as per previous. Flush and start again smaller concentration.

Ciao! È una carenza di P-K, causate da un eccesso di azoto, quindi fai un bel flush, e appena ha finito di bere, irriga con solo fertilizzante di fioritura, ma a mezza dose :) la volta dopo se si è ripresa potrai irrigare con una dose intera! Happy growing!

Looks like a nutrient burn to me, I'm not an expert so maybe wait for someone else to give you an opinion. I suggest to flush (you have to do it properly, using PhD water 6.5) then wait some days and restart with a light feeding. Good luck!

Lower leaves turning yellow and getting crispy Lower leaves are still turning yellow/brown. See photo. A couple weeks ago I got a greenhouse to protect the plant from the rain. Outside temperature has been lower and there hasn't been much sun (mostly clouds) so I don't think heat is a problem anymore. Don't know the pH. Help!

We've had some really warm weather the past few days. This morning, just before the lights switched off, i saw it was 31.1 degrees C in the grow tent. Are the yellowing leaves a concern? The yellowest leaves are really brittle. I don't believe they're under-waterd.

Nutrient burn?Hello I have one plant with yellowing leaves that are also curling downward. Only one plant of 6 has this problem, I suspect maybe this one is just sensitive to the nutrient rich soil? I am using fox farm happy frog and have added no other fertilizer. What to do, flush all?

Help! Why are my leaves turning yellow?Not sure why some of her leaves are yellowing on the edges. Is this due to environment? - 78.3°F | 64.8%RH Or a watering issue? - Currently she's drinking 8-9 cups a day through a sub-irrigated planter (EarthBox). Or maybe a deficiency? - See Logs for complete details.
