things are looking good mate, looks like the nute problem is solved the new growth is looking real healthy, you could start using some nutes again but start at quater or half strength till the plants get used to it, but you should be ok till corey's products turn up, as the plants are still young the compost should still have nutes in, they say the compost has enough natural goodness to keep the plants going for 6 weeks without adding anything, so you may not of added to much nutes, you may have just added to what was all ready their,
but the new growth looks good so i would say their is no nute problem now, and the sun really does make them grow so quick, the new growth is huge compared to the last pics, i wish my plants would start stretching, im hoping that cuz i messed the fim up that that has slowed the growth down and prevented it from having upwards growth, i think i took to much off and it stopped the growth while it grew new leaves in the place i fimd, their is new growth but its slow, im hoping it really takes off over the next week and bp nutes should help with the slow growth, ive stopped watering as well just sprayed the leaves instead i need to make sure the soils is not water logged, ive dug down the side of the pot and the soil feels slightly damp but not water logged, so not sure what to make of it,
your plants have certainly responded well to the topping, them new shoots are really taking off, you know what i might just top mind and get rid of that new growth, i think because this new growth is above the 2 nodes below it then the plant has put more energy into this top piece instead, topping might be my only solution,
