Hi Im currently growing my 2 babies there looking great about a month in under 150 W HPS light running 24 hours a day both of the plants look ok and are about 18' tall now I have a few question maybe i could get alittle assistance

1) on both plants some of the Bottom leaves show signes of yellowing and possible nute burn at the tips but thats only about 2 leaves per plant is this normal?

2) what height should my plants be to start budding under 12/12?

3) can i use all natural stuff to have a grow? currently using desert bat guano and was going to switch to cave bar or something with more potassium/phos


thanks guys !!
