Hi All
Will try to be brief. Six plants, in soil (biobiz)under 2 x 400 HPS. Plants have very good root system and nice fat stems and were doing ok using Advanced nutrients PH Perfect Grow and then Bloom. A week ago when two weeks into flowering it all went haywire. So far as I can tell, they are particularly suffering from mineral defficiencies - great loss of fan leaves, new growth stunted, v small leaves and bud really closely bunched together on new growth. Long story , short - experienced grower measured my PH with nutrients added and its 4.8. - low enough to cause multiple nutritional deficiency problems?
I have taken various action to try and solve the problems but cannot really afford to carry on with the lights on plants that show little promise of producing a worthwhile harvest. My mate reckons compost heap - but as Im more emotionally and financially involved I wonder if there is any mileage in pruning back and turning back to veg period under fluorescent (due to high cost of electric) rather than HPS?
Any views appreciated
