Drooping or stall right after transplanting

Likely causes, most likely first

1. LikelyTransplant shock

   Physical damageDeal with it this weekRead: Transplanting: when, into what, and avoiding transplant shock

   Fix: Move the root ball intact into pre-moistened medium of the same type and pH, water in with a mild solution, lower light 10-20% and keep RH slightly higher for 2-3 days. Mild droop for 2-5 days is normal; longer means root damage, waterlogging or a pH mismatch. Autos: sow in the final pot instead.

   Recovery: Turgor back in 1-3 days; new growth within a week.

   How to confirm it

   • Lift the pot and check moisture at depth. Lift the pot right after a full watering to learn its wet weight, then lift before each watering. Water when it is clearly lighter (about half the added water gone). Push a finger or a moisture probe 5 cm (2 in) down. Heavy for 3-4+ days with droop: overwatering. Very light with limp papery leaves: thirst.
   • Measure input pH and root-zone (runoff or reservoir) pH. Calibrate the meter with fresh pH 7 and pH 4 buffers, then measure the mixed feed and the runoff (containers) or reservoir (hydro). Soil and living soil should sit at 6.0-7.0, coco, rockwool and peat mixes at 5.5-6.5, hydro at 5.5-6.2. Track 3+ readings; one reading is not a trend.

2. Less likelyRecovery stall after topping, supercropping or heavy defoliation

   Physical damageLow urgencyRead: How long does a plant take to recover after topping?

   Fix: Give 3-7 days for photoperiods to recover from topping or HST before the next session; don't stack stresses. Prefer tucking to stripping leaves. On autos use LST only.

   Recovery: New growth resumes within a week.

   How to confirm it

   • Watch new growth for 5-10 days after one change. Make one correction at a time, mark the top node with a twist tie and photograph the same leaves every 2-3 days. Damaged leaves never recover; judge only new growth and whether the symptom stops spreading. Mobile-nutrient symptoms stop climbing within 5-7 days; immobile ones show in new leaves within 7-10 days.
