Did first topping yesterday, a week after transplant. Have given it a little bit of cultured biologix calmag in one watering and some recharge in a different watering. PPFD is at about 500/550, will keep it there for the next few days after topping. Have also applied rooted leaf agritech's silica skin as a foliar twice to improve cell strength. They need water about every three days which is on point
3/12 - raised light pffd, light watering around stem with calmag
3/15 - light watering
3/17 - watered 1/4 tsp recharge / 1/2 gallon
3/18 - topped and silica skin foliar
3/19 - watered
3/21 - raised light significantly to about 18inchs above canopy and raised intensity to 71% for approximetly 600 ppfd. Hopefully promote some more stretch while raising ppfd a little
3/22 - watered 1/4tsp recharge per 1/2 gallon
3/23 - rooted leaf agritech silica skin foliar
Add a wet towel. Higher your light and turn up the % of the light.
This will increase heat from light, but will also increase ppfd so be sure to move it above 60. Use a phototone app.. get the lux at the current hight and then you'll have something to go from by moving the light up and adding heat and inturn it will dry up the towel making a higher RH.
Good luck with your grow. Id also think of throwing a few quick 56 day autos if you're planning on long vegging. You'll have more than enough space unless you doing a Scrog.
