1st grow - CFL fridge grow - NL auto

Start of week 3, 4th node leaves are growing well and 5th have sprouted well. Isn't growing vertically too much as keeping lights quite close. Will prob start adding nutrients towards end of week Day 17 - decided to top the plant, want to keep it as short as possible due to the limited height available. Adjusted the light schedule so it gets a few extra hours before lights out, topped after the 4th node. After few hours of darkness and about 3 hours of light, plant seems fine Day 18 - first light schedule after topping, 3rd and 4th node leaves have changed, instead of being horizontal and almost floppy, they seem to have stretched up and became more firm. I'm guessing this is as a result of topping. Litre of ph'd water added Day 19 - new growth from topping is growing well, doesn't seem to have stunted plant in any way. Think I'll start adding nutrients next water Day 20 - quite an apparent smell now in the garage. Pistils are showing and plant doesn't seem stunted in any way. I know it's frowned upon, but added some miracle gro plant food at 1/4 strength. Still waiting on my biobizz stuff arriving. Plant is still growing on a daily basis
