Get an outlet tester....2 dollar toolo at your local hardware store...start testing all affected outlet...Also get a tool for twenty bucks called a greenlee..test for power in a given wire...ohms or amp meter for amperage and voltage and continuity..the latter can be expensive..Good luck..hope...
Might need to replace the breaker...hope your running industrial cords...I wouldnt use anything less than 10 gauge for my lights..Also check for gfi on the circuit,,might have to reset it
actually im thinking along the lines of addind not replacing...already have 1000w mh with red and blue bulb..Then stepping down my veg to flo's to compensate power bill
If you have to change it do it slow..your plant has adjusted to its current ph level being bad or good its used to it...make your changes slow over a wek of watering to drop 1.0
plants are tempremental...stress them early...crappy yield and potency
You can start new sprouts outdoors np..hurry!!!!
stay away from nutes tell your plants are kicken ass...you wont need any really now since flowering is just around the corner...hold off on nutes til flowering
