Learning coco coir!

Planted in a solo cup on the 28th of October, watered with no nutrients only adjusted to 6.0ph. Media: canna coco pro plus/perlite 25% Started to foliar spray with silica and liquid karma every few hours.

Now 14 days from starting jack. First feed on the 9/11/17 . First two weeks she recieved ph adjusted water, I’ll be using ph perfect advanced nutrients no extra brands. I will check EC and PH throughout the grow. I’ve been having big problems with coco coir so far, the seeds all germinate but seem to stop growing around week 3. I’ve used canna coco professional plus for this grow, usually used coco bricks and washed them before potting. Let’s hope for jack, please grow through the next week and keep growing.

All seems well so far growth has picked up over the last few days, a little discoloured leaves but she looks happy I think. She will be up potted to 20 litre fabric pots in the next day or so and I’ll feed her, leave her for a while to settle in and I’ll be back with updates. I’m now at the point where the plants stop growing using coco coir, although jack is alittle bigger than the others were, I have a little hope for jack now. Up potted and watered in today.

Not much change but there has been growth so I’m waiting on her filling out a bit more before training and main-lining. Topped her at 3rd node let’s start the training in a few more days.

Ok so as expected growth is at minimum. I know it usually takes a few days to come back from topping, but this can’t be the speed of growth in coco coir, it would take me months to match the size of my autoflowers in soil. I’ve done a lot of research on the subject and I’ve hit a brick wall, I have changed coco coir! I changed to a complete line of nutrients (advanced nutrients), I’m checking PH & EC though I don’t need to. Ph is always between 5.8-6.2 I’ve replaced my lamps 600w metal halide-veg, 600w hps-bloom, and added 200w cob led. I have a heater on an auto therm keeping the room at 25c during lights on, 20c during lights off. I keep a humidifier on all the time, humidity is the least stable as it has always been. RH50-75% the humidity without it is 35% but only if I have forgot to refill the humidifier, which has never been an issue before. I think I’m going to mix 50% coco coir with 50% biobizz all mix in my next grow I’m wasting my own time with this at the moment. There has been some growth over the last 2 days :) and she looks to be in good health, I’ve cut back on the nutrients at the moment, only watering with root stims and vitamins. I may have stunted her. Defoliate and started training

Taking shape nicely, I’ll wait on her stretching out a little more before topping. Topped at each end and removed a few more leaves, I’ll let her stretch out and then tie her down to the pot. I’m aiming for 8 tops around the pot and a few extra within the circle if the nodes stretch out enough.

Not much change still waiting on the new nodes stretching out for training, leaves are growing and look well. Overall she is growing a little slow, could be from the topping and removal of leaves. Removed the bigger leaves again. A few more days and the new nodes will be long enough to train.

Switched to 12/12 this week. Jack seems to be happy and growing well. Down to 11 tops as I removed one from the centre.

What a beauty 👌🏻

Been doing a little lst to separate the colas. Stretch has stopped and buds are forming fast.

Buds are stacking. Few of the leaves are misshaped, curling to a side with sort of necrotic spots.

Last week of big bud I think, overdrive from Thursday.

Buds are filling out lovely, lowering the nutrients.
