1. The Ph fluctuates constantly. Adding Ph down everytime it gets up there but only lasts a day until I must add again. Is this normal? LIQUID UP/DOWN LASTS LONGER THAN POWDER MIX. PH FLUCTUATION IS NORMAL BUT BEING IN THE HABIT OF CHECKING DAILY IS GOOD.

2. Ive just replaced the whole nute solution as it had a lot of green algae. Have read firther found that its light on water so have covered that better, is that the only cause of algae? How often are you ment to replace whole solution? THE CAUSES OF ALGAE TO GROW ARE AS FOLLOWS: LIGHT HITTING THE TRAY / NUTE TANK, WATER ABOUT 75 DEGREES FARENHEIT, AND ALSO STAGNANT OR DIRTY WATER. GET IN A HABIT OF FULLY CHANGING AND CLEANING YOUR RESIVOIR EVERY TWO WEEKS

3. I have no idea what temp the water should be at we have a heater that can set to any temp its at 20 degree at moment. SEE ABOVE

4. When should exhaust fan be on? I have it set up to same timer as lights, so its on when lights on. Temp stays between 25 -30 degrees celcius. WHILE SOME STRAINS APPRECIATE HIGHER TEMPERATURES, MOST SHOW OPTIMAL GROWTH SOMEWHERE BETWEEN 70-80 DEGREES FARENHEIT WITH THE LIGHT ON. WHEN THE LIGHT IS OFF IT SHOULD DROP 10-15 DEGREES IDEALLY.

5. One plant in particular is turning very yellow and not looking so good. All the leaves on all plants even healthy ones are curling downward, is this normal? What can you suggest? (pics Included) YOUR CAUSES FOR YELLING COULD BE A FEW THINGS. THE MOST LIKELY WOULD BE A NITROGEN DIFFICIENCY IN THE NUTRIENTS, OR POSSIBLE A PEST SUCH AS SPIDER MITES. LEAVES CAN CURL DOWN WHEN THE HUMIDITY IS TOO HIGH OR WHEN THEY ARE BEING OVERWATERED. SET WATER CYCLE TO "ON" FOR 15 MINS EVERY 4 HOURS AND INCREASE THE FREQUENCY BUT ONLY IF THE PLANTS SHOW NO SIGN OF DROOP.

6. Am using a CF meter for the nutrient level and it is always high, I add water however by next morning it is back to the same level, is this normal? I CANNOT ANSWER THIS QUESTION AS I DO NOT KNOW THE ANSWER.
