400w great white shark cabinet grow

first grow
Have a cabinet with multiple chambers... two for utility and 3 for growing.

1 mother chamber
1 clone chamber
1 main chamber (6 square feet)

170cfm exhaust fan, 400w hps ballast with a MH conversion bulb in it for veg.

2 DWC buckets in main chamber, air pumps, blah blah ect ask if u want any specifics.

the GROW:
general hydroponics nutrients, bunch of purified water, all the testers and crap... and six great white shark clones

DAY 1:
late on new years eve we receive the clones, immediately notice we were accidentally given clones in soil... I got as much of the soil as possible off of the roots and stuck them in hydroton and put them in the DWC buckets.

PPM: 200(GH flora series ratio 1-1-1)
PH: unknown, meter doesnt work
TEMP: about 80f
HUMIDITY: about 40
water temp: 66 or so

DAY 2:
Two of the clones are 100% dead. sooo dead. The others look ok but are a little droopy and the bottom leaves are turning yellow... I thought this might be a nute deficiency or a bug problem or something else entirely. I sprayed with neem oil and upped the PPM to 400 to see if that would help. temp and everything stayed the same.

DAY 3:
They look about the same. not getting any worse though. everything the same.

DAY 4:
They look a lot worse.... Really wilting and a lot of the leaves died. Sprayed with NEEM again, upped PPM to 600. starting to see some root growth on all the clones.

Day 5:
no worse no better, everything same. starting to think all the problems are probably because I have no frickin idea what the PH is...

DAY 6:
FINALLY got PH testers. put the PH between 6.5-7. Im pretty much color blind but I think I got it. seeing a lot more root growth.

PPM: 600(GH flora series ratio 1-1-1)
PH: 6.5-7
TEMP: about 80f
HUMIDITY: about 40
water temp: 68 or so

DAY 7:
They are starting to look better, they are growing, so are the roots. Still some discoloration in the leaves. The two back plants have a lot more root growth than the two front plants... this is strange.

DAY 8:
Same old shit. more root growth, looking a little healthier.

PICS BELLOW ARE FROM DAY 4. I will put up day 9 pictures tomorrow. please give any advice you have or comment, ask questions ect.

Your pH should be closer to 6.2.

The bottom leaves of a clone will turn yellow because the plant uses the mobile nutrients to help with root development.

As for the droopiness in the leaves, do you have air stones in the reservoir? Does any part of the net pot sit in the reservoir at any time? IMO, it looks like over watering.

I'm currently growing GWS, I must say they can take a lot in thier stride.

I've stressed mine to the eyeballs with temps going from 33c to 14c and they just continue to grow +subscribed.

yes I have two air pumps pumping connecting to air lines running throughout the cabinet. all the air lines are blocked except for the ones leading into the air stones in the tanks. So you think I should try adding more air pumps/air stones and/or adding some hydrogen peroxide?

the net pots never sit in the water. the water level is about an inch from the bottom of the pots.

and ya im going to lower the Ph probably tomorrow.

DAY 9: everything the same pretty much... switched the front plants to the back and the back to the front to see if the difference in root growth has anything to do with that.

couldnt get pics of the root growth but here are some pics... get root ones tomorrow.




the florescent tube light in the pic was just used to light the pictures. the last pic is a close up of the best looking plant. =)
