A real diagnosis, not generic tips
Post today's photos and Dr. BroGrowz works your plant up like a clinician, in plain words a first-time grower understands:
- Per-photo reads: up to 8 photos analyzed one by one, then a single combined verdict.
- Shows the reasoning: "top her today, tie her down tomorrow", you always see the why behind the call.
- Ranked possibilities: 2-4 likely causes with confidence bars, like a doctor's differential.
- One clear Move: what to do today, when to re-photo, what would escalate.
Healthy plant? He says so, credits what you did right, and won't invent problems.
A doctor who remembers your grow
Every diagnosis starts with your history, not a blank slate. The doctor reads his own past visits before writing a new one:
- Trajectory, not snapshots: problems get dated to what triggered them, trends get tracked visit to visit.
- He checks his own work: followed the last prescription? He notices and says whether it worked.
- Auto comparisons: today vs 24 hours ago and vs last week, on every entry.
- Summaries with scores: 3, 7, or 30-day write-ups that grade plant health, momentum, and your grower game.
He even does your paperwork
Every plan comes as seven Do / Buy / DIY cards: light, feed, water, environment, training, pest control, and next-stage prep.
- Do: the action with real numbers ("water 1 gal at pH 6.3 when the top 2 inches are dry").
- Buy: a real grow-shop product with the dose, only when you actually need one.
- DIY: the kitchen-cabinet version that solves the same problem for free.
- Logs build themselves: ask about watering and he reconstructs your full watering log from the journal, finished, dates and all.
Steer the grow. Ask anything.
Some days there's no photo to post, just a decision to make. Open Ask the Doctor and point the grow where you want it:
- Eight directions: force flower, hold veg, bushier canopy, transplant, harvest prep, and more, or free-type your question.
- Honest about timing: if a heat wave says wait, he tells you straight and gives the better window.
- The journal keeps up: flip to 12/12 and your plant's stage updates itself; every later visit follows the new direction.
5 asks per plant each week, fresh every Sunday.
A journal you'll actually want to keep
Four views of every plant: a flip-book journal, a working timeline, a calendar, and the summaries deck.
Weather that thinks ahead
Set your city once. Every entry stamps live conditions, tonight's low, and a 3-day outlook, so the doctor preps you for heat waves before they hit.

Read the doctor's case files
Real problems from real journals, written up so the next grower finds the answer faster: mildew vs sun glare, leaf-edge burn from high-pH water, the overwatering panic that needed nothing but patience.
How to tell the difference before you spray anything, and why one of them needs no treatment at all.
Grow season won't wait.
Every day you don't log is a day you can't compare against. Start the journal now, your harvest-day self will thank you.
