3 runs of clones, what the fuck....??????

now im not to new at this game, ive nad 5 good runs, every one of them pullin almost 1.5lb. per 1000w. then.....somthing has gone wrong.....

for the last 3 runs of clones they have auto flowered afte 10 days, now i know the basic q's to ask myself...

temp in veg. 85
ppm, 200 week 1 - 300 week 2
strain, creen crack
chems, sva svb
6" rockwool
light, 600w mh per 40 cuts
ro water

i always clean and bomb my rooms between my runs, never use same cubes, or coco caps.

so here are some ideas that i would like your advice on

#1 my ro filters have a lil bit of green alge in them, probably from the lights...bad water...?

#2 the veg chems, i have had for year and a half...bad chems....?

#3 some bacteria, that bleach and bug bombs cant kill....?

#4 .....? any other advice...?

i pay alot of over head, water, power, chems, cubes, clones
the last 3 lost runs, have put me in the poor house. if i dont figure it out, asap
i probably gonna have to shut it down, so please, pleeeeeeeeease, help a grower out....?

I'm no expert like some of these ladies & gentlemen, but I would suggest genetics. Try another variety if you haven't already.

I don't have experience with bad chems, but I know they do go bad with time. I don't know what the results would be.

i have tryed a few diffrent strains, and there on 24hr light
i had a few mothers under a t-8 and was feeding just water, and they were doin ok, the day i put them into reg rotation, the flipped over, im convinced its the chems,
i was just hopping to hear some agreements,

anybody know the shelf life of super nuits sva svb....?

You may be right, a year and a half seems like a long time. I would just think it would show as a deficiency of some kind, rather than send them into flower. Like I said tho, I have no experience. Good luck.
