I am crap at growing
Got like 7 lowryder #2s with a couple of durban sknks seedling with them
I know this grow pretty much goes against all advice
matt side of aluminium foil
shoeboxes lined with bin bags and foil
mix of some AP compost with polystyrene crumbled in it for drainage
125 2700k enviro
200w 6700k with half the tubes dead =100w
225w fluoro
temps are high 20s but humidity is high

2 plants ine one pot and 1 in the other are a bit stunted
yellowing leaf tips on older leaves turning brown
other leaves sslightly lighter green than healthy plants
these plants are getting just as much light water and heat as each other
could the foil be causing this?
