Oddly I have some one month old Qrazy Train, Green Love Potion and Cotton Candy plants that are otherwise healthy except they all have varying degrees of dwarfing or stunted appearance. Internodes are only 3/8" apart or less under plenty of CFL and low wattage (100w) MH light veg chamber. Plants have lush emerald green color and display no trace element problems. F&D hydro, gravel medium, PH 6.5 with Eco-Grow nutes I've used for years without problems. Humidity, temps and air circ. is good. Am a veteran but haven't seen this before. Weird but they look almost bonsai without having been pinched or stressed in any way. Main stems are super thick and lots of leaves and branches but the tallest one is only 7-8 inches and only a 6-7 inch footprint due to very short fan leaf stems. It may be that they're still coming out of the seedling stage and just look that way for now. Anyone else have this experience? Thanks for any input.
