2nd grow starting indoors

i was wondering if anybody elese on here has used a small greenhouse inside to start there plants?

when my growbox was killing my seedlings due to heat and ventalation issues i moved them into this greenhouse it has interchangeable shelves im using 6 cfls 4 26 watt and 2 15 watt. i have a large fan blowing cool air into the bottom and they get sunlight during the day. i also had ph issues i was unaware of but this seems to have been solved thanks 2 the helpful advice of the kind people on these boards:). so after all these problems i had 3 seedlings left and then i had 1 more sprout and yesterday another sprouted the new seedlings are the healthyest ones i have started yet. i put white bed sheets over the greenhouse at night to help reflect the light back onto my plants and the temperature seems to stay fairly constant around 75 degrees farinhieght in the greenhouse.

so im wondering if anybody elese has used teqniques similar to this to start seedlings? i hope to start clonning them as soon as posible. i have root hormones and very basic knowledge of clonning how old do they have to be before i can start cloning them? also any feedback/help/sugestions are welcome ill post some pics in a few mins

heres a couple pic of what im workin with

heres 3 of the seedlings im worried about the first 2. the first 1 had no new problems aside from the previous burns on the lower leaves untill i checked on it just now its got brown spots forming on the leaves but not from the tips like before. the second 1 still hasnt recoverd that great from the heat stress/high ph n its scrawny n stressed lookin and the 3rd seedling is about a week old and i think its doin awsome why cant the others recover n do as well as this seedling:( lol

oh and 1 more thing my mom was telling me something about companion plants like putting marrygolds near tomatoe plants is good for both them i have a few onion plants and some bell peper plants growing in the same greenhouse does canibas have any helpful companion plants? if so does anybody know what they are both my mom and i are wondering this

lookin at the trouble shooting threads its either still my ph or some kind of nute deficiency. i just checked the ph treated water ive been using and its gone through the roof again somehow just sitting in the bucket i mixed it in. so now my question is how to i keep the waters ph from changing back? or do i hafta make a new batch of water every time i water? damn my tap water lol i flushed my plants again with the water thinkin it was still the same ph now realizing this is the problem they are havin but then how come the new sprouted plants havent been affected im confused now

in the last few hours the spots have gottin worse i just did a soil runoff test n my soil ph is higher then the waters ph i havent given them anything but water since i first started having problems

so after ph treating some more water and flushing again it doesnt seem to be getting any worse but i havent seen any improvement yet the 1st plant in those 3 pics has quite a few more spots on it then it did in the pic like i said it got significantly worse over a very short time last night i was very surprised by that i hate seein my seedlings on such shakey ground it sucks

so im thinkin it looks like either calcium or boron deficiency effecting this plant but im still not sure what it is. is it old enough that i can feed it? or am i guna run into problems like i did before if i do? any sugestions or ideas as to what this is n what i can do about it? u cant see it in the thumbnail but if u enlarge it u can see brown spots with darker edges
