Cbdhemp808's Comparison Grow - HI-BISCUS SIP Bucket Vs. Nursery Pot

DAY 53 => DAY 1 of flower

The SIP plant has reached 3-1/2 ft tall, so I transferred both plants to the flower house.

DAY 52: HEIGHT... SIP - 41.00", POT - 45.00", Δ -4.00
DAY 53: HEIGHT... SIP - 42.00", POT - 45.50", Δ -3.50

SIP rez was down to 3/4" so I topped it up with 2 quarts of fert water. The POT was also light, so I gave it about 1 gal of fert water which produced a lot of runoff. I am feeding now with both high-N liquid fert and soluble KMAG (K, Mg, S). I will also start adding DTE's seabird guano (P) by adding 2 Tbsp to a gallon of water and letting it steep for a couple days, shaking the container several times. EDIT: Also kelp powder in with the seabird guano.

I am taking two comparable clone cuttings from each plant, but not the main stem.

You're managing them to be almost the same size! I'm surprised the SIP isn't much bigger! Looking great on both!

Yeah, I'm still trying to figure that out. There was a hiccup early in the grow, because I should have started fertigating after 2 weeks. By day 26 both plants were obviously hungry. I think the SIP plant got stunted because she fell into a negative feedback loop—nutrient and water uptake go hand in hand, so the SIP plant started to shut down. By day 32 or so, the SIP plant had stopped growing. By day 34 I started feeding and the SIP plant sprung back into action.

I think the reason the POT plant didn't suffer as much is because she was on the wet/dry cycle, whereas the SIP plant's roots were sitting in water she couldn't absorb.

So, had I fed early we would quite possibly be seeing a different situation now. The big question now is, what will happen as these two plants get close to harvest time. We shall see!
