All 5 have been topped with lower branches LST'ed. 1 was bent over at main stalk and tied down. All but 1 are a foot tall. The 1 odd ball has been shorter and much bushier than the other 4 since early on. Will continue topping the taller 4, and hopefully short stuff will catch up. The leaves were starting to get ripples/wrinkles and turning a lighter green. Switched from liquid PH up and down (viagrow) to natural baking soda and lemon juice, after reading the liquid could have adverse effects on certain soils. Noticed positive changes within 24 hrs. Foliage looks greener, and they don't look so wore out at the end of the light cycle. Plan to switch to flower once plants reach 18-24 inches, so hopefully in a few more weeks. Had to install carbon filter due to smell
