Day 68 Autoflower - Problem or not ? (first grow)

Hey,

The fan does blow directly onto this plant, it's pretty close.
No idea of PPM as I don't have a meter
PH going in is 6.5 and PH in the runoff is the same, 6.5
Feed every 3 days, 2L per feed
I do not get run-off at 2L, it takes 2.5L if I was aiming for runoff (biobizz mentions there's no need to water to run-off when using biobizz)

Seems to be doing quiet well since the flush

Do you feed based on the day or the plant and the pot weight?

Basically do you feed when they need it or just every 3 days regardless. they may be drying out too much causing ph issues, especially with this plant being closest to the fan, it will dry out faster than the others. especially considering you watering them to saturation (flushing) helped

also see if theres a way to make it so the fan is indirectly blowing around the tent if it's very close

Hello again,

It's day 78 now for this plant. I have not used nutrients for the last 10 days, just watered every 2 - 3 days or so as needed with 2L of water.
Overall the plant doesn't look too great compared to others of the same age. It is Expert Seeds Northern Lights Auto

Does it look like it will be much longer before harvest going by these pictures?
I wonder if I should start feed with nutrients again or stick to water only.
