As we enter week five we notice some of the plants pre flowering. But not all so I decide to stick with veg nutrients until all are showing pre flowers. Half way through the week and the rest of the plants are showing pre flowers. Just in time as the plants that had pre flowered earlier on in the week are showing slight Newt burn on the tips suggesting It is time to change to bloom newts which holds less nitrogen. The magnified picture are of the pre flowers forming ( two little fuzzy hairs). Interesting fact: it takes thousands of those little fuzzy hairs to form just one bud.
