You should be starting your first day of week 4 today, i believe. You should really be seeing the white puffy balls of fur now. Theyve got what i like to call" their big girl hairs" now


Right now is when nitrogen should be getting lower and phosphorus higher and then start of week 5 you keep going but they should also start getting more potassium then too. Basically now is when you really want to start switching over to full bloom nutes. What i would also be doing right around now is taking a real good look at my bud sites everywhere. Look at the canopy from above and make sure there arent any big fan leaves blocking bud sites. And make sure you have a nice even flat canopy, all your tops are the same height. Then look under the screen and make sure there is 1. Ample space to allow for adequate air circulation and transpiration. And 2. Any
smaller, underdeveloped branches that look like they will be less than 2nd harvest trim, remove them now and just let the plant use that energy for the better buds. By 2nd harvest, what i mean is that i carefully watch everything above the screen and check the trichomes with the scope daily until the tops are ready to harvest. I prefer to harvest when the trichomes are a thick milky white and there is the odd trich head starting to turn yellow/amber (1 out of every 10 maybe). But this is what i enjoy, you harvest when you please. Ive harvested good indicas late mostly amber and that was my bedtime medicine right there. Anyways, watch the trichs and go down the stalks until i see some of the trichs are still clear, and then i chop a couple nodes above that if the nugs feel right in the hand. Then after taking the tops I'll remove the screen and let the rest of the plants continue to mature but you must watch closely, sometimes they need another 2 weeks and sometimes it only days. But this is what i personally do, just to give you some ideas and since i start new clones at the same time i start flowering, waiting the extra time to get a 2nd harvest doesnt bother me because ive already got new plants waiting to flower. Thats the beauty of perpetual.
