Hi Guys
something has gone wrong with my plant. It about 7 weeks old and was 'ok' before this major change happened.
Ill explain the setup i have and perhaps somebody can take it from there..
Its a flood and drain hydroponic system; the tray contains the plant which is home to a ROCKWOOL cube and clay balls/rocks are also filled in the tray which is fed water via a water ring and drains back into the reservoir.
the PH level is kept between 6.3 & 6.5.
the nurtient level is reading between 800 PPM HANNA - 900PPM HANNA OR 1.7 EC
its also connected to a air pump with two large airstones for oxygen.
400 WATT HPS LIGHTING 18hours on 6hours off.
Fan (Oscilating at LOW/MEDIUM speeds.
Intake and exhaust fans also.
room temparature is between 25/29 degrees celcius.
plant gets flood and drained for 2/3minutes twice during daylight hours.
the light is the corrent distance from the plant.
I dont know what the hell is happening.. can somebody let me know what it could be? need EXPERT advise here the leaves just went twisted all of a sudden and curley 'leave edges curl inwards'. & droppy branches.
colour wise i cannot see any signs of nutrient burn; no burnt edges.. just nice green leaves 'except for a few newest on the top which were a little yellow and curly a day before this happened.
not sure if its overwatering or under watering? weak plant? i dont even know what strain it is or its name..
whats happening to it???????????
