@retireandgrowpot sorry mam [emoji106]
I havent grown in soil for about a year now- but if you can pick up an accurate 8 soil ph probe.
If you know the ph of your soil thats half the battle.
Your last plants dont look all that bad- the picture of the leaf you posted looks like a phosphorus deficency to me.
And the plants look a bit short- maybe the leds were a bit close? That can stop them from gaining some height.
So are you following technafloras feed schedule? Feed schedules are nearly always made for photoperiods and even at that theyre on the strong side.
So its normal for auto growers to start at 1/4 strength and work up from there.
Havent used technaflora myself but i think some of these growers have
@BayLee420 @Brew712 @Watergunz @Maria Sanchez any info on technaflora for autos guys?
