noob study and advice pls

Hi i have one plant on the go as a learning curve for myself it could turn out to be male but im on a budget of nil and scraping by so here is my first attempt at a grow.
Any help would be great dont know what strain it is the seed came from some weed i bought its about 5 weeks now since planting and up untill now i had it under 2x 2 ft t8 18 w bulbs and it seems to be going ok (i think)
take a look at the pic s


I have recently got 2 x20 watt philips tornado 1350 lumen bulbs it says there 115 watt equivelent and am planning to put them on the plant and i think the 2 ft tube has about 1150 each tube so roughly i think i have about 5k lumen is that about right for one or two plants in a small 2 ft x 2 ft space does the plant need to be transplanted soon i also have some tomato plant food 4.0 2.0 5.0 when should i start using this have noticed a small yellow spot on a middle leaf the past two days but it has not got any bigger or spread since all help welcome pls

hi just an update the bottom two single leafs are turning brown and are ready to fall off and the next two threeblade leafs are starting to go a lighter green with a hint of yellow i think there on the way out now but new growth is good and healty soo far is it normal too loose these leafs or is there sumthing wrong thanks in advance..

Are u feeding them

i am watering when the soil is dry about every 3 days and once a week feeding with tomato plant food 1/4 capfull in a 2 l bottle dilute as it says on the label,
have only fed them twice but the browning of theese leafs started before i fed them for the first time
When i water i add water till i see water coming out of the end of the pot and let it finish draining till the drips stop
i am starting to see a couple of leafs in the middle of the plant devolope some small yellow spots and some leaf tips turning slightly brown/red .
I am growing in gen purpose potting compost that drains well, the plants are about 5/6 weeks old now when should i think about transplanting here are some pictures.. any help would be great thanks

hi leaves on lower nodes colour is draining from them and they are turning yellowish with brown leaf tips help

I know you said your on a budget of nil, but you need some better neauts than what your giving them. I use botanicare pro grow, pro bloom, liquid karma, hydro-plex, bud candy, and clearex to flush. This gets great results but is a bit expensive. You could get by with pro grow, pro bloom, and liquid karma. About $60 bucks total for a quart of each which would more than do for your grow of these plants. :rasta:

plants looking good now i think ,,, have followed the instructions and fim the plants instead of topping them i am getting new growth after 3 days and nice dark green bushy growth below the are about one and a half feet tall now and are in 6 inch pots about two weeks now. i have got them this far on two 2 ft t8 tubes 18w each.

i have now bought a 150w power plant cfl 2700k for flowering and am wondering when to switch it over to 12/12 the plant is a bagseed it looks like a cross breed of indica and sativa have not yet needed to feed the plants and there still doin good.

will the plant still grow when i flower it? as im a little worried about height of my growspace and i have some bio biz blooming nuterients will i give them everytime i water as it says on the bottle ? currently im watering twice a week when they seem dry any help on these questions would be great thanks in advance.....

here we go
