Progress Report/advice welcome (PICS)

ok well..... seems ive kinda gotten the hang of growing.. i finally got my plants unstunted . they are in a stable temp zone , phed water, cfls , regular poting soil nothing else

so im down to 5 plants... from 7-9 ... along the way theyve seperated themselfs dramaticly in growth and ive taken the liberty of removing the ones that didnt look like they were goin anywere.. so im down to 5 plants varying in size from 2-7 inches

at the moment the plants look like growth has resumed( previosly stunted bad) but they seem to still have/get yellowing tips that slowly consume the leave... right now it seems to not be causeing too much problems but it shouldent happen ? below pics. any opinions /suggestions welcome

stats
Temp 67-84
Water ph 6.5-6.8
Soil - regular pottin soil
Small countainers
Light - 125 watts of CfL
Humidity 15%-60%
Ventalation - 1 outtake fan
Space - 43 inches L X 36 inches H X 20 inches D

Pics of the plants provided below... right now im just looking for some feedback to let me know how im doing and what i can be doing better. right now the things ive selected for improvement are as follows :

Ventalation - planning on getting 2 computer fans 120mm low noise 40-50 cfm

Light - Deciding if i should go with a small hps or get more cfls. due to the small space heat could be an issue ( size of cab above)

Containers - already have 2 gal containers i just wanna get some more light befor transplant ( right now most containers huddled around cfls )

As For Growing STyles i think i will just stick with natural growth no LST no SCrog the plants seem fragile and they just came out of stunting.. dont wanna put them back into it... or worse... i will just keep them short and flower early... kinda like lolipoping i guess ?

And thats it for this grow... for next grow i plan to experiment with New soil with a mix of perlite/other, LST/sCrog, Cloning, NuTes.

any comments or advice is appriciated... if u need further info or pics just ask

Hmmz ..........

I wold flush out the soil look like there is to much

Nitrogen Deficiencies:
Plants will exhibit lack of vigor, slow growth and will be weak and stunted. Quality and yield will be significantly reduced. Older leaves become yellow (chlorotic) from lack of chlorophyll. Deficient plants will exhibit uniform light green to yellow on older leaves, these leaves may die and drop. Leaf margins will not curled up noticeably. Chlorosis will eventually spread throughout the plant. Stems, petioles and lower leaf surfaces may turn purple.

wow.... that paragraph was so usefull.... i had thought that nitrogen deficiency was a possibility but i assumed a heatissue i had or light issue was more likly... but that paragraph seems to have hit it perfectly...

why would i flush the soil if it has a deficiency? shouldent i get some nutes? or do u think that the water/soil is causing the uptake of nitrogen to be reduced?
(note: earlyer in the grow i did not ph the water) ( it was around 7.5 or so )

well if nitrogen is just sitting in the soil you wont to wash it all out. the roots don't wont to use up any more of the nitrogen b/c of its deficiency.
