need some help first legal med grow in cali, worried....

So I have a 4x8 tray that i have put about 25 plants that started off as seedlings...
I recently topped all of them and put the tops in the cloning machine and put the plants into the flower room with 2 1000 watters over the tray of smart pots filled with hydrotin...

first few plants to go into the tray were very tall and healthy but i became too impatient and put the other two strains into flower also...

the ppms started off at 1200 when the large plants were the only ones on the tray...
when i brought in the small ones i dropped it down to 1000 ppms

they came from a veg tray sitting at around 700-750

the first two days everything looked alright but now the small ones have been in there for three days and they started to get really lime/ yellow leaves...

I emediatly started my C02 cuz i was kinda holding out on it to save money...

now the tops look week and are starting to bend over and not stretch to the light like they did before...

added a little cal mag today but not sure what to try...


Trying to aviod flushing but may have to..


here are a few pics...



the ones on the far right side of tray went into flower june 1

middle only four days into flower.... and are about seven inches tall...

they felt quite dry and flat yesterday
thought this was the start of nuit burn but the tips look healthy... i thought tips are supposed to curl with nuit burn...
humidity is around 45 and heat is around 84
lots of air movement..

might just be shock from topping and flipping to flower... but they grew three to four inches real quick when i put them into flower..

how are your temps? everytime i put mine into flower i get the lime green look at the base, and midway up the leafs, but im thinkin that its just normal new growth man...i did see a twisted leaf, could be high temps, or PH fluc. or even just a fluke, only saw one.....IMHO everything looks good. though i am curious as to why the tops are leaning over like that. how is your ventilation and temps??

temps 85

but got c02 runnin on regulator 1500 ppms

hmmm...and it is hydro...man, i dunno wish i could help more. still look healthy right now though.

we will see when lights turn on today...

is it bad to lightly foliar spray when your plans look like this or do u think it will help them recover from this weird skinny bent tip/ yellowing/ flat paper like dry lower leaves and crinckly upper leaves.

the new leaves on the very tip look very very skinny... like tooth pic length and almost as skinny as a tooth pic...

you can always run some string from a ceiling joist and give the tops a lil support...dont have a clue as to why it may be doing it though...its what i would do...if everything else looks good and they look healthy, just seem to have weak tops, then why not eh?

when i start flowering and at like the first or second weeks, all my new growth does the same.skinny leaf pattern. but eventually widen out.

awsome thanks for the help man
