WRINKLED LEAVES!!!!!!! What do you think. THANKS FOR STOPING BY

Thanks for stoping by and sharing your time and knowledge


My plants are about 21 days old from seed Still on 18/6

They are in 3x3 rockwool cubes, which were soaked in 5.1 for 24 hrs.

Out of 8 Plants, Same strain, God bud. Half of them have wrinkled leaves, Slight tip curves. The other 4 look GREAT.

RES. info

PPM 420

P.H. 5.2-6.2 It Drifts

Run off --------Sample taken after 20 sec of run off from feeding

PPM 420

PH 6.2
MY QUESTION IS THIS

Do you think the High ph nature of rockwool is causing the ph within the medium to raise to an unacceptable level??

Or do you think the Wrinkled leaves are being caused by cal -mag diff.

Or possible over watering?

I am using RO water with starting PPM of 40, Canna substra soft water nutes - THIS SHOULD TAKE CARE OF ANY CAL MAG ISSUES?



Feeding Currently 2 hrs after lights turn on, for 2 mins. And two hours before lights off, for 1 minutes ( run of starts after pump being on for JUST 16 SECONDS)

Did you flush your rockwool first?
I think I remember somebody saying last week it's good to flush them with PH'ed water before using, but IDK really, I'm a soil guy.

Rockwool needs to soak in ~5.5 water then be FLUSHED with fresh 5.5 to 5.8 water with or without a little bit of nutes in it. If not flushed the calcium carbonate from the limestone in it will screw up the PH which usually leads to a phosphorus deficiency in the plants due to a lockout scenario. I however usually equate wrinkled leaves with too high a nute level...

PH too low, ppm too high. Canna rhizotonic to start then very weak nutes. Should soak/ buffer rock wool first, i would've just used rhizo. Temp? RH ?
