What was your ROOKIE mistake?

Mine was not letting the hot water cool down after boiling it for a hot pepper solution to kill spider mites.

Or

Not planning for cold nights and putting a heater in a grow box then frying my gorgeous plants.

Not learning about LST til my 3rd grow

I chopped my first crop according to breeder flower times. Marked it on the calendar. If I had only known.......

Trusting even one person.

Using tap water exclusively, on my second grow. And also not letting it out for 24 hours before use. The plant got salt toxicity which resulted in a cal mag deficiency. Back then I couldn't figure out how to fix it so I chopped early. So far it's been my worst mistake.

Buying nutes from a retard..lol and using well water.no having meters..lol

trying to fix deficiencies...that were really caused by pests

Planting against a hedge. Excellent camoflage, but a bit of a scramble when the tractor arrived to cut it. Luckily the 60 odd plants were in pots. Unfortunately when I stood them back up they were 2-4 foot taller than the hedge. Camouflage Fail

Lets be honest
Being lazy... under planning the design and setup of grow spaces which only wastes time and money on replacing and redesigning existing systems with better functioning/more professional systems but that's how most learn.
Wasting time not growing the best of the best. Keep track of which clones come from which strains/plants so you know exactly the type of flowers they will produce.
Keep searching until you find better and better genetics.
Over-watering clones.
Not monitoring the pH/ppm of the water/fertilizer solution =(deficiencies/lockouts/burns)
Being suckered into the pressure that my plants need ever supplement and over spending on nutrients. & then I found CNS17 and never looked back!
I could go on for ever

growing in a warm attic an getting spider mites... they multiplied so fast that the plant was engulfed in webs after only 5 days after i noticed anything was wrong

Put a mirror in for light reflection years ago. Not much worse than that

This is my third year of running a perpetual flowering room.
The first year I was chasing my tail with PH meters, snake oils and supplements, expensive MJ soil mixes, dechlorinating water.
I put a bunch of seedlings in some Vermafire soil mix and it was WAY too hot!

I live in the Rockies, so maybe my water is good, but I threw away all the testing equipment, quit buying expensive, already mixed MJ soils like Happy Frog, Vermafire, etc.
I grow in Sunshine #4. Simple peat/perlite blend. Costs about 1/4th of the expensive soil mixes.
I use Jack's Classic nutes and it couldn't be simpler.

I don't make rookie mistakes.

Not reading the Nutruient chart correctly feeding 1/3 strength the entire grow.

putting unfinished compost on a 7 foot tall bush. It rotted straight through the stem, killing the plant in less than a week or two.

Wow......I made all the rookie mistakes....all of them. Drowned my plants, burnt them to shit with nutrients, cut the tips on ALL the leaves in veg, tried every advanced growing technique all at once......and somehow they survived my abuse and gave me a whopping ounce total from two plants.

I now have a cabinet full of useless nutrients, PH up and down, PH testers, etc. etc. I too only feed with Jack's Classic, I don't yank leaves, and the only "advanced" growing technique I use is Uncle Ben's topping.....and an occasional super-cropping if the plants get too tall.

Heating mat, killing $150 worth of seeds.

Then just 'cause I obviously like killing seeds, I stored several packages of them in my basement to suffer through hot then cold weather in dampness.

My first 3 to 5 grows I chopped early because I ha no idea what I was doing, and letting my space get overcrowded before switching to 12/12.

Phing my soil soil grow down to 5.2 - 5.6 and thats for hydro and aero ponies and the correct ph for soil is 6.2-7.0

Adding nutes to seedlings a week old
