31 days into flower, I have slowly upped the cf to 1.8 since my last post, I have added a bit of Cal/Mag and upped the pk and treacle. My lights will come on as I am writing this, so we will see soon if yesterdays biggest feed to date has had any adverse effects. Video is my run off left to stand in shopvac over night. As you can see it is 'Alive' and bubbling away. What is going on does not smell like yeast or Vinegar, it smells like 'Clean fresh Compost'. So I expect the runoff is producing CO2 and Methane. CO2 is good, roots can absorb it. With the Methane there is possibly some Ethylene being produced, which may have some very positive benefits as far as plant chemistry and suppression of masculine traits? The gases bubbling off the runoff 'Soup' would not be difficult to Identify with a couple of wash bottles and a few readily available reagents. I ain't got the time, or the kit. There are definitely a few different organisms at play here as you can see different structured plaques forming on the water surface, and different foams forming with the bubbles. Just took photo's, everything looks good except Blue Sherbalato, Developed a kink in top leaf, that could be a couple of things, I shall work it out. (highered light a bit, dropped c/f, pushed cola away from light centre, and I shall let this pot dry out a touch, it has been happy till now.) Every thing else is looking OK, all got a touch of tip burn. Canna Coco sometimes does not have enough N for grow, and almost always too much N in flower so I expect a bit of tip burn especially in high calyx to leaf hybrids. The plants are using around 2 litres of water + food per day with a slight + or - on c/f with first runoff. Ph going in at 5 to 5.5. First runoff is 6.8 I will keep watering till runoff hits 5.8 or lower so it usually takes between 3 and 4 litres of nutes. per day. Hate being this wasteful with nutes , not enough going on in the garden to use it all out there yet, so down the drain it goes. I have thought about re-circulation, if I was bigger and running clones maybe. The Blue Sherbalato has shown me I got to start treating these plants as individuals and tailor their treatment accordingly. The GTH have changed their smell, the Lemon is still there but fuel and floor polish is becoming more dominant in 3 of the plants. My plants are in 10 litres of Coco in 15 litre felt pots rolled down. Maltezerz, Orangesicle GTH 1, . plus the Scott's OG will run out of pot space so I will top them up to the 15 litre. Got to make decisions on the cuts of these plants soon. I hate culling plants before the parent has finished its cycle.
