right on Al. i appreciate your input alot, thanks.
no wucking furries, mate.
Gotta tell ya, in my 15 years of advising growers, I have found that the number of magic sauces on any given grower's shelf is inversely proportional to the grower's experience and success rate! Far too many new growers haven't gotten past the 'more is better' mindset. When things don't go well, too many growers rush off to a hydro shop to get a cure-all potion.
90% of the time the problem is much simpler, normally related to basics that have been overlooked, such as getting room conditions (temp, RH, ventilation rate, etc) and watering rate right. Noobs persistently overfertilise, overwater and don't set up a room's ventilation and temp control properly.
Plants are not V8 engines, where ramming more fuel and air into the thing universally gives better results. Plants are very different. There's a bell curve to it. There's 'not enough,' 'just right' and 'dead.'
Your good critical thinking skills will serve you well in the grow op. When reviewing a shelf full of magic sauces, remember that unless the sauce maker gives you a sound scientific basis for their sauce, inclusive of telling you what the main active ingredient is, you can bet that the main ingredient is profit- for the sauce sellers.
Grower anecdotes are almost always unreliable. Growers WANT these things to work and normally overestimate the value and performance of magic sauces. The placebo effect of magic sauces is unusually powerful in this arena.
Moreover, the joker behind the counter at a hydro shop is NOT normally a reliable source of information. His/her job is to sell stuff. If they really knew what was going on, do you think they'd be tending the counter at a hydro shop? Of course not! They'd be running a productive grow op and earning many times the minimum wage they get at the hydro shop, with much less time investment.
Get your room conditions right-
first. Make sure the watering rate suits the medium you're using. Once those are in place, your op will yield well consistently.
