Here’s a typical autoflower feeding schedule using T.A. (GHE) Tripart on soil with organic compost (2.5-1.5-2), assuming you're growing in 10–11L pots under decent light and aiming for a balanced grow:
---
General Guidelines:
Start feeding after 2 weeks from sprout (or earlier if you notice deficiencies).
Feed every other watering (e.g., water – feed – water – feed).
Use pH 6.0–6.5 for soil.
Mix nutrients at 50–75% strength to avoid burning, especially for autoflowers.

Example Feeding Schedule (per Liter of Water):
Week Micro (ml) Grow (ml) Bloom (ml) Notes
1-2 (Seedling) 0.5 0.25 0 Just water if soil looks rich; otherwise very light
3 (Veg starts) 1 0.75 0 Start feeding slowly
4 2 1 0.5 Ramp up – signs of preflower
5 (Early Flower) 2 0.5 1.5 Shift to bloom support
6-7 (Mid Flower) 1.5 0.25 2.5 Main flowering phase
8 (Late Flower) 1 0 2.5 Cut grow/micro, focus on bloom
9-10 0 0 0 Flush – only water

Tips:
Always observe your plant – autos can be sensitive.
Adjust based on leaf color, clawing, tip burn, or deficiencies.
Consider adding CalMag if your water is soft or symptoms appear.
