newby BIG light question

[allbuds]

I have two plants that are around a month old.

they are about half of a foot tall and bushy!

i had them on 24 hours at first two weeks and then i put them on 18/6 for about a week and a half and the last couple days ive had them on 12/12

i was told that they should grow twice as fast on those hours and then flower when its ready i was just doing this two speed things up a little

is anything gonna go wrong? ive also been watering them with blackstrap mallases ive also heard acouple things about that to.

i was just wondering if any body can help me?

my lighting is 4 T 8 tubes thats somewhere around 4000 lumens and also 4 23 watt compact fluro's thats another 1600 lumens each so thats somewhere around 7000 lumen

i also have a 32 gallon tanjk where there being grew in so size is a problem but ive done things to fix that!!

Within a week or 2 they'll start showing pistals and from there the plants know what to do. They might double in size the first 3 weeks of 12/12. Depends on the strain how much they stretch and how long they take to show their sex.
