hi was hoping someone could confirm this issue for me i was thinking possible boron deficiency or nute burn, maby salt buildup in soil as have never flushed. my ph has been pretty much dead on 6.5 the hole grow.
plant is auto blue pyramid from pyramid seeds and is 6 weeks old
light is 600w hps about 15 inches away temps have been around 28c has been a bit hotter at the top of the canopy recently sometimes getting to 31 but not much i can do about it at the moment.
nutes are bio bizz grow, bloom and top max have read controversial things about top max but as had already bought decided to use.
plants are in 3 gallon pots im watering every couple of days when the pot gets light.
i was using just under full strength nutes as the plants seemed to be hungry and growing very fast and hadnt had any problem until 6 days ago when brownish patches started to show up next feeding i fed half my regular nutrient ratio thinking was nute burn but the problem has spread so lead me to think will be a deficiency. runof ph is about 6.5 but im not so sure i trust my ph metre is a cheap 4 pound one not digital.
