yea ive been worried about outgrowing.
i have an off topic also, i did a res change for them both yesterday. the taller plant took to it great. the smaller one did also, BUT it developed a TINY bit of root rot. so when i do res changes. i add nutes to water. let sit for about an hour, then check/adjust ph. im thinking because i let the water get ROOM temp when i put in new res. it was probably room temp a few hours. so like 70-72 degrees. is it possible this small exposure to room temp water caused the slight root rot?
no other plant is having a problem, i use hydroguard with my General hydroponics.
