I use FF nutrients and you are 100% correct. I accidently used 3/4 strength and still experienced some nutrient burn. Definitely start slow 1/4-1/2 recommended dosage and ease it up as needed. If you start with full recommended dosages you will more than likely end up with nutrient burn at a minimum.I wouldn't be able to help with autoflower setups necessarily. But what i will say to you and anyone who has never used FF nutes to always use 1/4 to 1/2 like 'upnsmoke' said. Never use full strength, you'll nute burn them.
I used only Maxicrop seaweed extract through veg and added FF tiger bloom 1/2 strength 2nd week of flower. MJ plants love both. But that's just me. I do everything right the first time and never had trial/error/ nutrient issues.
Im just using some organic soil from a local farmers produce shopI've heard ffof(soil) is hot. Nutes are as hot as you mix them. Around 1/4 to 1/2. May need to use mag supplement. What soil you using?
Im running a 24x24x55" tent im just using some organic soil with perlite and vermiculite already in it. I purchased it from a local farmers market. Im using 5 gal grow bags, a 300 watt led with an added 75 watts of cfl (i simply added the cfl to make myself feel better i dont really think it was super necessary) i got the fox farm trio for nuets, the strains im currently running are "cash crop" and "afghan kush ryder" the are in their first week of life. I germinated straight into pots so i didnt have to transplant them. Been watering with rain water only at this point (which hopefully it rains soon cause i only got about 10 gallons) other than that thats about it. Sonce they are in early stages i usually run them between 85 and 90 degrees with an rh of around 75- 90% obviously i will tone this down after the first week or two. I have been running them on a 24/0 schedule for the time being but im going to cut them down to 20/4 in the next 3 days when i start my nuets. I may have gave you some un needed info but thats what ive got going. This is my first grow as well so any advice helpsI'm using ffof with perlite & lime added, I'm also growing autos. Using around 100 ppm of cal-mag and around 300-500 ppm of nutes. Used Grow Big, Tiger Bloom. Same ppms whole grow, changed nutes per life cycle of plant (veg,stretch,bloom). Working for me. My temps are low 70s to 60 at night. @Useless89 what's your setup?
Yeah i got a small 8 inch fan in the upper corner blowing air and i have a 4" carbon filter with inline fan. I can feel it pulling air through the tent walls. I usually leave my lower vent a tid bit open so it can suck in fresh air easily.Be sure to have your ventilation in order. Keep your tent intakes passive and have an extraction fan strong enough to pull the tent walls, in a little. On top of that, have another fan blowing the tops around. You just want your leaves swaying, not blowing directly on the little ones but definitely moving the leaves some - this will strengthen your stems. I've read autos like cool tops & warm roots - my Mazaar didn't perk up until she was below 80*, she had a stressful veg! I'm no expert but I haven't bought, in a while!
Honestly my fan is actually pretty quiet i can barely hear it outside the closethttps://www.amazon.com/PHC-Enterprise-Variac-Variable-Transformer/dp/B006NGI8VS/ref=sr_1_1?ie=UTF8&qid=1478217058&sr=8-1&keywords=variac
Been using one of these for a speed controler, on my scrubber. It may save you some noise, if your fan is pulling too hard.
