So I'm just starting week 4 in bloom and have run into problems which are just getting worse. It started with yellowing lower fan leaves but has now progressed to upper leaves with necrotic spots and some leaves drying and falling off.
I'm now worried they won't make it to harvest.
Set up is.
440w led lighting
Dehumidifier Rh around 40%
3x circulation fans
120cfm extraction fan
Lights on 28 degrees lights off 18 degrees.
5 gal pots
Canna terra pro soil with 10% extra perlite.
Biobizz nutes
Grow
Bloom
Topmax
Heaven
Cal mag
Been feeding full recommend dosage every watering. Ph6.3
Problem has developed over the last week.
I'm pretty certain it's not incorrect watering as I follow emilyas watering guide.
After some advice here I tried lowering calmag dose.
Checked pH pen calibration and I've started using bottled water as my tap water is very hard.
Yesterday I performed a bit of a flush I watered with 5 gal plain Esther then watered with nutes an hour later so I ended up with a 5gal run off from each plant.
Nothing I have done seems to help and I'm at a total loss as to what to try next.
Any advice would be excellent thanks.
