No resources to sustain army FH Isis

Ok so when I advance FH isis, I gather like 1500 gold or something, then after the prosperity ends, I send the most villagers to wood, leave 4 on food for vill support and rest build migdol/siege/ then to gold.

The problem is, I still don't have enough wood eco to sustain chariots + siege and I don't have enough food for anything else. How can I support an army + siege? My build order is:

- starting 2 + pharaoh on food, research HD

- 2 gold

- 4 food (6 total)

- 1 builds monument, house, temple, then spam houses till maxed

- 6 food (12 total)

- AQ to gold till I can advance, research pickaxe and flood of the nile

- When I advance, 2 wood villies build armory, rest all go to gold till I advance

- I up nephtys then send almost all to gold, cast prosperity

​

Then we've come to the problem. Priest siege is good only vs atty, right? What do I do?
